CVE-2022-0172Network attack vector

Metadata disclosure via GraphQL IP-restriction bypass

Published Jan 18, 2022 · Updated Aug 2, 2024

Improper authorization in GitLab allows remote attackers to read IP-restricted public-project issue, merge request, and milestone titles via GraphQL. The public record identifies the GraphQL path but does not name the resolver or exact omitted authorization check that fails to enforce project IP restrictions. Exposure requires an IP-restricted public project and a request from outside its allowed range; the reported consequence is limited to title disclosure.
