CVE-2026-65984
Overview
CVE-2026-65984 is a known-severity vulnerability. It was published on August 18, 2026.
Technical Description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. 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.
