{"schemaVersion":3,"id":"CVE-2026-53709","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-10-13T14:32:12.137Z","modified":"2026-10-16T21:59:50.970Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.8,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.8,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.8,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00603,"percentile":0.48138,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-14T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00603,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00603,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00603,"percentile":0.48138}],"last30":[{"date":"2026-10-14T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00452,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00603,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00603,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00603,"percentile":0.48138}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-287","name":"Improper
