CVE-2026-59766: Gitea CVE-2026-20800 sibling endpoints not covered: revoked user still reads private repo objects via `/api/v1/user/starred` and private issue titles via `/api/v1/user/times`

July 21, 2026

CVE-2026-20800 fixed private-info leakage to revoked users only for the notification endpoint. Two sibling endpoints that return data keyed on the caller’s own relationship still do not re-check repo access at output time:

  • GET /api/v1/user/starred — getStarredRepos() computes a per-repo permission but still lists every starred repo (no filtering), so the full repo object (full_name, private, clone_url, ssh_url) of a now-inaccessible private repo is returned.
  • GET /api/v1/user/times — ListMyTrackedTimes() queries by UserID only and LoadAttributes brings in the issue (title, state), leaking private issue titles after revocation.
