Versions 0.13.4 and below have a broken access control vulnerability which allows authenticated users with write access to any repository to modify labels belonging to other repositories. The UpdateLabel function in the Web UI (internal/route/repo/issue.go) fails to verify that the label being modified belongs to the repository specified in the URL path, enabling cross-repository label tampering attacks. The vulnerability exists in the Web UI's label update endpoint POST /:username/:reponame/labels/edit. The handler function UpdateLabel uses an incorrect database query function that bypasses repository ownership validation. This issue has been fixed in version 0.14.1.","published":"2026-02-19T02:33:09.877Z","modified":"2026-08-12T03:51:26.892292703Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"gogs.io/gogs","fixedVersion":"0.14.0"}],"fix":{"url":"https://github.com/gogs/gogs/commit/643a6d6353cb6a182a4e1f0720228727f30a3ad2","label":"gogs/gogs@643a6d6"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25229.json"},{"type":"ADVISORY","url":"https://github.com/gogs/gogs/security/advisories/GHSA-cv22-72px-f4gh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25229"},{"type":"FIX","url":"https://github.com/gogs/gogs/commit/643a6d6353cb6a182a4e1f0720228727f30a3ad2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:26.892292703Z"}}
