CVE-2026-66853
Gitea restricted-user organization metadata disclosure
Reported by gitea · Published October 14, 2026
Gitea's user organization-list API includes Limited-visibility organizations for authenticated restricted accounts without applying the visibility restriction enforced by the single-organization endpoint. A restricted user can list a known user's public organization memberships and retrieve limited organizations' names, descriptions, and avatars. This exposes organization metadata that should be hidden from the requesting account.
