{"schema":"threatline.record/2","record":{"id":"CVE-2026-89430","aliases":["GHSA-hcgw-r9gf-8mph"],"summary":"Gitea push mirror SSRF and forced writes to internal Git hosts","details":"Gitea validated a push mirror's remote address against the `[migrations]` allow and block lists only when the mirror was created. Each synchronization passed the stored address directly to `git push`, so a name that later resolved to a blocked or internal address was still reached. A user with administrator access to a repository, which includes repositories they create themselves, could aim push mirror synchronization at internal Git services and force-push the repository's contents to them.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-89430","source_modified_at":"2026-10-07T20:16:04.169Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Gitea","vendor":"Gitea","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.27.3","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00187,"percentile":0.07906,"score_date":"2026-10-23"},"published_at":"2026-10-06T19:23:52.198Z","modified_at":"2026-10-07T20:16:04.169Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-89430","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T20:16:04.169Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-89430","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-hcgw-r9gf-8mph","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39010","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39426","tags":["patch"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-28.0.0/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v28.0.0","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":"total","assessed_at":"2026-10-07T20:15:42.946496Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-07T20:16:04.169Z","content_hash":"5d52622ff134f4328a8c780a6cf7c29dde9579c9ef3215024c0b2b65ff57396d"}}
