Prior to version 0.31.0.0, the application fails to immediately revoke active user sessions when an account is deleted. Due to a logic flaw in the backend design, account state changes are enforced only during authentication (login), not for already-established sessions. The system implicitly assumes that authenticated users remain trusted for the lifetime of their session. There is no session expiration or account expiration mechanism in place, causing deleted accounts to retain indefinite access until the user manually logs out. This behavior breaks the intended access control policy and results in persistent unauthorized access. This issue has been patched in version 0.31.0.0."}, {"lang": "es", "value": "CI4MS es un esqueleto de CMS basado en CodeIgniter 4 que ofrece una arquitectura modular, lista para producci\u00f3n, con autorizaci\u00f3n RBAC y soporte de temas. Antes de la versi\u00f3n 0.31.0.0, la aplicaci\u00f3n no revoca inmediatamente las sesiones de usuario activas cuando se elimina una cuenta. Debido a un fallo l\u00f3gico en el dise\u00f1o del backend, los cambios de estado de la cuenta se aplican solo durante la autenticaci\u00f3n (inicio de sesi\u00f3n), no para las sesiones ya establecidas. El sistema asume impl\u00edcitamente que los usuarios autenticados siguen siendo de confianza durante la vida \u00fatil de su sesi\u00f3n. No existe un mecanismo de caducidad de sesi\u00f3n o caducidad de cuenta, lo que provoca que las cuentas eliminadas retengan acceso indefinido hasta que el usuario cierre sesi\u00f3n manualmente.
