Technical details
An incorrect authorization check in GitLab CE/EE allows an authenticated user holding a project-scoped fine-grained Personal Access Token to modify group integrations outside the token's intended scope. The vulnerability results from insufficient authorization validation in the integration management logic. A network-based attack requires prior authentication and affects versions 19.1–19.4.1.
