GitLab vulnerability analysis and mitigation
Overview
An issue has been discovered in GitLab CE/EE affecting all versions before 17.10.7, 17.11 before 17.11.3, and 18.0 before 18.0.1. The vulnerability, identified as CVE-2025-0993, was reported through GitLab's HackerOne bug bounty program by researcher pwnie (GitLab Release, NVD).
