What is CVE-2026-14210?

A vulnerability discovered in GitLab CE/EE could potentially allow an authenticated user, who possesses a project-scoped fine-grained Personal Access Token, to permanently delete or modify group-level labels. This issue arises from improper authorization logic regarding the ownership scope validation of labels, thereby enabling unintended manipulations by users with restricted project-level access.
