CVE-2026-34570

Full vulnerability record from the local CVENow database.

Description

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. 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.

      "value": "CI4MS es un esqueleto de CMS basado en CodeIgniter 4 que ofrece una arquitectura modular, lista para producción, con autorización RBAC y soporte de temas. Antes de la versión 0.31.0.0, la aplicación no revoca inmediatamente las sesiones de usuario activas cuando se elimina una cuenta. Debido a un fallo lógico en el diseño del backend, los cambios de estado de la cuenta se aplican solo durante la autenticación (inicio de sesión), no para las sesiones ya establecidas. El sistema asume implícitamente que los usuarios autenticados siguen siendo de confianza durante la vida útil de su sesión. No existe un mecanismo de caducidad de sesión o caducidad de cuenta, lo que provoca que las cuentas eliminadas retengan acceso indefinido hasta que el usuario cierre sesión manualmente. Este comportamiento rompe la política de control de acceso prevista y resulta en acceso no autorizado persistente. Este problema ha sido parcheado en la versión 0.31.0.0."
