CVE-2026-73126
Gitea private workflow badge token scope bypass
Description
Gitea's Actions workflow status badge endpoint does not enforce repository-read scope or the public-only restriction on the token authenticating the request. A token lacking read:repository, or restricted to public repositories, can retrieve the latest workflow status of a private repository accessible to its owner. This discloses private workflow status beyond the token's intended delegated permissions.
