CVE-2026-34570 Vulnerability Summary

CVE-2026-34570: 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.

Assessing the Risk of CVE-2026-34570

Access Complexity Graph

The exploitability of CVE-2026-34570 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-34570

No exploitability data is available for CVE-2026-34570.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-34570, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

CAPEC Common Attack Pattern Enumeration and Classification

  • Leveraging Race Conditions CAPEC-26 The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.
