Attack-Flow Graph

Executive Summary

This vulnerability in GitLab CE/EE allows an authenticated user to access sensitive credentials and tokens without proper authorization checks. It affects versions from 10.1.0 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 due to improper checks on internal data emission endpoints.

Detection Guidance

This vulnerability involves improper authorization checks in GitLab's internal data emission endpoints. To detect it, check GitLab logs for unauthorized access to sensitive credentials or tokens. Look for unusual API calls to internal endpoints or requests bypassing expected proxy routes. Verify all GitLab versions are updated to patched releases (19.1.8, 19.2.6, or 19.3.2).

Impact Analysis

An attacker with access could steal sensitive credentials and tokens, potentially leading to unauthorized access to systems, data breaches, or further exploitation of connected services.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR and HIPAA requirements for data protection and access controls.

Mitigation Strategies

Upgrade GitLab CE/EE to version 19.1.8, 19.2.6, or 19.3.2 or later to address the improper authorization checks.
