CVE-2022-39233Public exploitNetwork attack vector

Authenticated branch-prefix modification via unchecked REST authorization

Published Oct 19, 2022 · Updated Apr 22, 2025

Missing authorization in Enalean Tuleap 12.9.99.228 through 14.0.99.23 allows remote authenticated users to alter GitLab branch prefixes. The PATCH /gitlab_repositories/{id} handler accepts an integration visible to the caller and writes its branch-prefix setting without verifying Git administrator authority. A low-privileged account and visibility of an integrated GitLab repository are required; exploitation changes that integration's branch-reference behavior.
