{"schema":"threatline.record/2","record":{"id":"CVE-2026-53709","aliases":["GHSA-m8rv-5m6m-32ff"],"summary":"MCP Context Forge: Hardcoded default JWT_SECRET_KEY shipped in source and .env.example enables pre-authentication platform admin token forgery","details":"MCP Context Forge is an MCP gateway and administrative platform. Prior to 1.0.2, mcpgateway/config.py and .env.example ship a known JWT_SECRET_KEY, while verify_jwt_token() accepts HS256 tokens signed with that key and get_current_user() creates a platform administrator when the token subject matches PLATFORM_ADMIN_EMAIL and REQUIRE_USER_IN_DB is false. A remote unauthenticated attacker can therefore mint accepted administrator tokens without a database account. While the vulnerable signing key remains configured and the platform-admin bootstrap remains enabled, forged access survives password rotation, account deletion, and session revocation, allowing administrative disclosure, modification, and service disruption. This issue is fixed in version 1.0.2.","categories":["Unclassified"],"product":"mcp-context-forge","vendor":"IBM","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-53709","source_modified_at":"2026-10-16T21:59:50.970Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"mcp-context-forge","vendor":"IBM","versions":[{"status":"affected","version":"< 1.0.2"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/IBM/mcp-context-forge/security/advisories/GHSA-m8rv-5m6m-32ff","source_modified_at":"2026-06-15T09:25:14Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"ecosystem":"pip","name":"mcp-contextforge-gateway"},"range":"⁠<= 1.0.1"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00603,"percentile":0.48225,"score_date":"2026-10-23"},"published_at":"2026-10-13T14:32:12.137Z","modified_at":"2026-10-16T21:59:50.970Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-53709","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T21:59:50.970Z"},{"source":"GitHub Advisory Database","url":"https://github.com/IBM/mcp-context-forge/security/advisories/GHSA-m8rv-5m6m-32ff","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-06-15T09:25:14Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-53709","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/IBM/mcp-context-forge/security/advisories/GHSA-m8rv-5m6m-32ff","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/IBM/mcp-context-forge/commit/2af690f894b6e35f5f21190fdab1505f023a5272","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/IBM/mcp-context-forge/releases/tag/v1.0.2","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-16T21:59:27.134623Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T21:59:50.970Z","content_hash":"b4cc7c248a7b7d65cbc4fda43e4dd8910390f364ea31dab045ac9961cb2ae502"}}
