Executive Summary

This vulnerability in GitLab EE affects versions from 13.9 before 18.10.8, 18.11 before 18.11.5, and 19.0 before 19.0.2. It allows an authenticated user with Security Manager-role permissions to manage project security configurations even when the relevant feature is disabled. This happens due to incorrect authorization enforcement under certain conditions.

Impact Analysis

The vulnerability could allow a user with Security Manager-role permissions to change project security settings without proper authorization, potentially leading to unauthorized modifications of security configurations. This could weaken the security posture of projects managed in GitLab.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade GitLab EE to a fixed version. Specifically, update to version 18.10.8 or later if you are using the 18.10 series, 18.11.5 or later if using the 18.11 series, or 19.0.2 or later if using the 19.0 series.

This vulnerability affects versions from 13.9 before these fixed releases, so ensuring your GitLab EE instance is updated beyond these versions will prevent exploitation of the incorrect authorization enforcement.
