Unauthenticated file disclosure via repository API traversal
Published Sep 12, 2026 · Updated Sep 12, 2026
Path traversal in GitLab CE/EE 18.7 through 19.1.7, 19.2 through 19.2.5, and 19.3 through 19.3.1 allows remote attackers to read server files. The repository commits API confines paths incorrectly and fails to enforce authentication, allowing crafted requests to escape the intended repository path and return arbitrary host files. No account or user interaction is required, and disclosure is limited to files readable by the GitLab service; direct file modification is not established.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=18.7 <19.1.8
- Affected versionversion=19.2 <19.2.6
- Affected versionversion=19.3 <19.3.2
