- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

The French CERT has published an advisory covering multiple vulnerabilities affecting GitLab Community Edition and Enterprise Edition. The vulnerabilities span three affected version ranges: versions prior to 18.10.7, versions 18.11.x prior to 18.11.4, and versions 19.x prior to 19.0.1. The flaws enable attackers to trigger remote denial of service conditions and bypass security policies. GitLab has released patches; defenders must upgrade affected instances to patched versions 18.10.7, 18.11.4, or 19.0.1 or later. The advisory references seven CVE identifiers but provides limited detail on exploitation status or attack vectors in the public summary.
