Detailsinfo

A vulnerability was found in ci4-cms-erp ci4ms. It has been declared as critical. Affected by this vulnerability is an unknown part. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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 deactivated. 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 deactivated 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, representing a critical security flaw. This issue has been patched in version 0.31.0.0.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-34572 since 03/30/2026. The exploitation appears to be easy. The attack can be launched remotely.
