Executive Summary

This vulnerability in GitLab EE allows an authenticated user with a custom role and compliance framework administration permissions to improperly configure and execute a specially crafted compliance pipeline across group projects due to incorrect privilege assignment. It affects versions from 17.0 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2.

Detection Guidance

This vulnerability requires checking GitLab versions and user role permissions. Verify if your GitLab instance is running versions 17.0 to 19.4.1 without the latest patches. Check for users with custom roles holding compliance framework administration permissions.

Impact Analysis

An attacker with the right permissions could misuse this flaw to run unauthorized compliance pipelines, potentially leading to data exposure, compliance violations, or unauthorized access to sensitive information across group projects.

Compliance Impact

This vulnerability could lead to unauthorized data processing or exposure, violating compliance requirements such as GDPR or HIPAA by allowing improper access or manipulation of sensitive data through crafted pipelines.

Mitigation Strategies

Upgrade GitLab EE to version 19.2.8, 19.3.5, or 19.4.2 or later to address the improper privilege assignment issue.
