CVE-2026-53911 Vulnerability Summary

CVE-2026-53911: Cerebrate before version 1.37 allowed the id primary key field to be supplied through request input during CRUD edit operations and certain custom entity patching flows. In affected entities that did not explicitly mark id as inaccessible, an authenticated attacker could submit a crafted edit request containing the id of another record, causing the save operation to update that unrelated record instead of the record identified by the route parameter. The issue affected several entity types inheriting permissive mass-assignment defaults, including User, Role, UserSetting, LocalTool, PermissionLimitation, and EnumerationCollection. Since UserSettings edit functionality was reachable by any authenticated user, exploitation could allow unauthorized modification of records within the same entity type, with impact depending on the affected endpoint and writable fields. Cerebrate 1.37 fixes this by stripping id from request input after marshalling callbacks and by globally marking id as inaccessible in the base AppModel entity. The discovery of those potential vulnerabilities are inherited from initial finding from Jeroen Pinoy additional support from AI-Assisted Optus 4.8 (the commit wrongly assign Claude Fable 5 as the model switched) and coordinated by Andras Iklody.

Assessing the Risk of CVE-2026-53911

Access Complexity Graph

The exploitability of CVE-2026-53911 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-2026-53911

No exploitability data is available for CVE-2026-53911.

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-2026-53911, 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
