{"id":"CVE-2026-63378","state":"PUBLISHED","title":"TAKO AI Agent for Okta: Authenticated Python execution through validator bypass","description":"TAKO AI Agent for Okta is a local-first AI agent that helps Okta administrators query tenant data using natural language. Prior to 3.0.1-beta, any authenticated user with a valid `fctr_session` cookie can submit arbitrary Python source in the `script_code` field of `POST /api/react/execute-script`, without administrator privilege. In `src/api/routers/react_stream.py`, the source is stored with `skip_discovery=True`, bypassing AI-based content filtering, and is passed to `validate_generated_code` in `src/utils/security_config.py`. `BLOCKED_PATTERNS` recognizes direct `__import__` calls but misses the import name passed as a string, `getattr` is in `ALLOWED_BUILTINS`, and the AST checker handles `ast.Name` and `ast.Attribute` targets but fails to handle `ast.Call` targets. Dynamic `getattr` call chains through `__builtins__` therefore evade validation. The `_write_temp_script` helper writes the accepted code to disk, and `asyncio.create_subprocess_exec()` executes it as the application process user, which is root in the default container. Command output is returned as Server-Sent Events through `GET /api/react/stream-react-updates?process_id=<id>`. The resulting container compromise can disclose environment secrets including Okta API tokens and the JWT key, expose the SQLite database, and permit backend-service pivoting and persistence. This issue is fixed in version 3.0.1-beta.","publishedAt":"2026-10-30T22:19:39.743Z","updatedAt":"2026-10-30T22:19:39.743Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["fctr-id okta-ai-agent"],"affected":[{"vendor":"fctr-id","product":"okta-ai-agent","versions":[{"version":"< 3.0.1-beta","status":"affected"}]}],"references":["https://github.com/fctr-id/okta-ai-agent/security/advisories/GHSA-r9q7-6784-7rc6","https://github.com/fctr-id/okta-ai-agent/commit/3b5ccaff8423cdfa6d26f5e133c01b8b71148df4","https://github.com/fctr-id/okta-ai-agent/releases/tag/v3.0.1-beta"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-30T22:26:06.415Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/63xxx/CVE-2026-63378.json","commit":"f02cde01d713f161fa6518ef321d5dace5470571","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-63378","state":"PUBLISHED","datePublished":"2026-10-30T22:19:39.743Z","dateUpdated":"2026-10-30T22:19:39.743Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-16T17:39:30.170Z"},"containers":{"cna":{"title":"TAKO AI Agent for Okta: Authenticated Python execution through validator bypass","descriptions":[{"lang":"en","value":"TAKO AI Agent for Okta is a local-first AI agent that helps Okta administrators query tenant data using natural language.
