A vulnerability, which was classified as critical, was found in GitLab Community Edition and Enterprise Edition 16.0.0 (Bug Tracking Software). Affected is an unknown code of the component Public Project Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22.
