Executive Summary

This vulnerability in GitLab CE/EE allowed authenticated users with guest-role permissions to access test report contents they were not authorized to view due to improper access control enforcement.

Detection Guidance

This vulnerability affects GitLab CE/EE versions 18.4 before 19.0.5, 19.1 before 19.1.3, and 19.2 before 19.2.1. To detect it, check your GitLab version using commands like 'gitlab-rake gitlab:env:info' or 'cat /opt/gitlab/version-manifest.txt'. If your version is within the affected range, the system is vulnerable.

Impact Analysis

An attacker with guest access could view sensitive test reports they should not have permission to see, potentially exposing confidential or proprietary information.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, which may violate compliance requirements under GDPR (data protection) and HIPAA (health information privacy) by exposing confidential test reports to unauthorized users.

Mitigation Strategies

Upgrade GitLab to a patched version: 19.0.5, 19.1.3, or 19.2.1 or later. After upgrading, verify the fix by checking the version again. Ensure guest-role users cannot access unauthorized test report contents.
