In 1.3.2 and earlier, POST /api/refresh in server/api/auth/index.js falls back from current user data to decoded.groups, including when the user is deleted or groups is zero, and POST /api/heartbeat in server/api/index.js re-signs inbound JWT claims without validating the current database record. An attacker who possesses a previously issued privileged refresh cookie or access token can continue minting privileged JWTs after account deletion, disablement, role removal, or demotion. Continued refresh-cookie rotation can extend the stale session and preserve unauthorized access to user management, project manipulation, runtime configuration, scripts, and backdoor-account creation. This issue is fixed in version 1.3.3.","published":"2026-08-18T20:17:20.557","modified":"2026-08-18T20:17:20.557","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/frangoteam/FUXA/commit/4fa47d0a2a856ed34f427f472fb4450f86e7749b","label":"frangoteam/FUXA@4fa47d0"},"references":[{"type":"WEB","url":"https://github.com/frangoteam/FUXA/commit/4fa47d0a2a856ed34f427f472fb4450f86e7749b"},{"type":"WEB","url":"https://github.com/frangoteam/FUXA/pull/2379"},{"type":"WEB","url":"https://github.com/frangoteam/FUXA/releases/tag/v1.3.3"},{"type":"WEB","url":"https://github.com/frangoteam/FUXA/security/advisories/GHSA-rg7m-xwqc-mjw6"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T20:17:20.557"}}
