GitLab patched a critical unauthenticated remote code execution flaw affecting self-managed instances, with coverage reaching back many years of releases. The issue matters because a compromised GitLab server can expose source code, CI/CD secrets, and production deployment paths, turning a DevSecOps platform into an enterprise-wide attack vector. Later reports indicate the flaw is already being targeted in the wild, increasing urgency for patching and verification.
