Summary
CI4MS: Account Deletion Module Full Persistent Unauthorized Access for All‑Roles via Improper Session Invalidation (Logic Flaw)
Details

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.
