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.","state":0,"publishedAt":"2026-10-13T14:32:12.137+00:00","modifiedAt":"2026-10-16T21:59:50.97+00:00","affected":[{"ecosystem":"Vendor product","name":"mcp-context-forge","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"IBM\",\n                    \"product\": \"mcp-context-forge\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.0.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/IBM/mcp-context-forge/security/advisories/GHSA-m8rv-5m6m-32ff","https://github.com/IBM/mcp-context-forge/commit/2af690f894b6e35f5f21190fdab1505f023a5272","https://github.com/IBM/mcp-context-forge/releases/tag/v1.0.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53709","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53709","identifiers":["CVE-2026-53709"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
