{"schema":"threatline.record/2","record":{"id":"CVE-2026-66874","aliases":["GHSA-5xp7-r6cr-39ff"],"summary":"Gitea required Actions check bypass through skipped workflows","details":"For pull request events, Gitea reads workflow definitions from the pull request head and posts a synthetic skipped status when workflow branch or path filters exclude execution. A fork pull request author can supply a workflow matching a required status context but deliberately prevent it from running. Because skipped statuses count as success, branch protection or organization-required workflow checks can appear satisfied without the mandated workflow executing; no runner or maintainer approval is required for this path.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-66874","source_modified_at":"2026-10-14T15:12:51.792Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Gitea","vendor":"Gitea","versions":[{"lessThanOrEqual":"1.27.2","status":"affected","version":"0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xp7-r6cr-39ff","source_modified_at":"2026-08-29T19:09:45Z","fetched_at":"2026-10-23T20:37:03.234832Z","package":{"ecosystem":"go","name":"gitea.dev"},"range":"<= 1.27.2"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xp7-r6cr-39ff","source_modified_at":"2026-08-29T19:09:45Z","fetched_at":"2026-10-23T20:37:03.234832Z","package":{"ecosystem":"go","name":"gitea.dev"},"version":"1.27.3"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00262,"percentile":0.17038,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:36:06.090Z","modified_at":"2026-10-14T15:12:51.792Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-66874","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T15:12:51.792Z"},{"source":"GitHub Advisory Database","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xp7-r6cr-39ff","fetched_at":"2026-10-23T20:37:03.234832Z","source_modified_at":"2026-08-29T19:09:45Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-66874","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xp7-r6cr-39ff","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-1.27.3/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39005","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39018","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":["release-notes"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-14T15:12:30.376099Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T15:12:51.792Z","content_hash":"5bb1eba14ba6efd11144ab3023fbb69ec9e9176f6b9dfa06319cc187fd8c35db"}}
