Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-863.
Summary
Gitea's Actions workflow status badge endpoint does not enforce repository-read scope or the public-only restriction on the token making the request. A token without read:repository, or limited to public repositories, can retrieve the latest workflow status of a private repository its owner can access. This exposes private workflow status beyond the token's intended permissions. Gitea through 1.27.2 is affected (CWE-863, CVSS 3.1 score 4.3, Medium).

Description from the CNA
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.
