CVE-2021-22228Public exploitNetwork attack vector

Authenticated disclosure of project details

Published Jul 6, 2021 · Updated Aug 3, 2024

Improper access control in GitLab allows remote authenticated users to read otherwise restricted project details through GraphQL queries. GitLab has not published the affected resolver or the specific authorization operation omitted when GraphQL resolves those project-detail fields. A low-privileged account and network access to /api/graphql are required; affected releases are before 13.11.6, 13.12 through 13.12.5, and 14.0 through 14.0.1, and the published impact is disclosure only.
