Summary

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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of go-gitea/gitea published their own advisory on GitHub. Reviewed sources take precedence over it.
