Attack-Flow Graph

Executive Summary

This vulnerability in GitLab EE allows an authenticated user to access information from unauthorized projects due to improper handling of untrusted content in the AI-assisted code review feature.

Detection Guidance

To detect this vulnerability, check GitLab EE versions for affected releases (19.1 before 19.1.3 or 19.2 before 19.2.1). Verify if AI-assisted code review functionality is enabled and review logs for unauthorized project access attempts.

Impact Analysis

An attacker with access could view sensitive project data they are not authorized to see, potentially leading to data leaks or unauthorized information disclosure.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating compliance requirements for data protection such as GDPR or HIPAA, which mandate strict access controls and data confidentiality.

Mitigation Strategies

Upgrade GitLab EE to version 19.1.3 or later if using 19.1.x, or to version 19.2.1 or later if using 19.2.x. This addresses the improper neutralization issue in the AI-assisted code review functionality.
