CVE-2021-22248Network attack vector

Unauthenticated pipeline information disclosure via authorization failure

Published Aug 23, 2021 · Updated Aug 3, 2024

Improper authorization in GitLab CE/EE allows remote attackers to view restricted pipeline information in public projects. The pipelines page returns some pipeline details without enforcing the project's members-only pipeline visibility restriction; GitLab has not published the responsible code locus. Exploitation requires a public project with pipeline access restricted to project members, and the reported consequence is read-only disclosure of pipeline information.
