Executive Summary

This vulnerability in GitLab CE/EE allows an authenticated user with developer-role permissions to run CI/CD pipelines on a protected branch without proper push permissions. It occurs due to incorrect authorization checks during pipeline reference validation.

Impact Analysis

An attacker with developer access could execute unauthorized pipelines on protected branches, potentially leading to code execution, data leaks, or service disruption. This bypasses intended access controls.

Compliance Impact

This vulnerability could violate compliance requirements by allowing unauthorized code execution or data access. It may breach integrity controls in GDPR (data protection) and HIPAA (health data security).

Mitigation Strategies

Upgrade GitLab CE/EE to version 19.0.6, 19.1.4, or 19.2.2 or later to address the improper authorization issue in pipeline reference validation.
