CVE-2025-11429
Full vulnerability record from the local CVENow database.
Description
A flaw was found in Keycloak. Keycloak does not immediately enforce the disabling of the "Remember Me" realm setting on existing user sessions. Sessions created while "Remember Me" was active retain their extended session lifetime until they expire, overriding the administrator's recent security configuration change. This is a logic flaw in session management increases the potential window for successful session hijacking or unauthorized long-term access persistence. The flaw lies in the session expiration logic relying on the session-local "remember-me" flag without validating the current realm-level configuration.

"value": "Se encontró una vulnerabilidad en Keycloak. Keycloak no aplica inmediatamente la desactivación de la configuración de reino 'Recordarme' en las sesiones de usuario existentes. Las sesiones creadas mientras 'Recordarme' estaba activo retienen su vida útil de sesión extendida hasta que expiran, anulando el cambio de configuración de seguridad reciente del administrador. Esto es un fallo de lógica en la gestión de sesiones que aumenta la ventana potencial para el secuestro exitoso de sesiones o la persistencia de acceso no autorizado a largo plazo. La vulnerabilidad reside en la lógica de expiración de la sesión que se basa en la bandera 'recordarme' local de la sesión sin validar la configuración actual a nivel de reino."
