      "value": "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."

      "value": "FUXA es un software de visualización de procesos basado en web (SCADA/HMI/Dashboard). En 1.3.2 y versiones anteriores, POST /api/refresh en server/api/auth/index.js recurre de los datos del usuario actual a decoded.groups, incluso cuando el usuario es eliminado o groups es cero, y POST /api/heartbeat en server/api/index.js vuelve a firmar las reclamaciones JWT entrantes sin validar el registro actual de la base de datos. Un atacante que posee una cookie de actualización privilegiada o un token de acceso emitido previamente puede continuar generando JWTs privilegiados después de la eliminación de la cuenta, la deshabilitación, la eliminación de roles o la degradación. La rotación continua de la cookie de actualización puede extender la sesión obsoleta y preservar el acceso no autorizado a la gestión de usuarios, la manipulación de proyectos, la configuración en tiempo de ejecución, los scripts y la creación de cuentas de puerta trasera. Este problema está solucionado en la versión 1.3.3."
