{"schema":"threatline.record/2","record":{"id":"CVE-2026-73800","aliases":["GHSA-r9ch-mqjm-g67v"],"summary":"Gitea reusable workflow secret exposure in pull_request_target","details":"Gitea resolves local reusable workflow files from a fork's head commit when a trusted base-branch workflow runs for a pull_request_target event. A fork author can modify a referenced reusable workflow so attacker-controlled code executes with the repository and organization secrets available to that event. Exploitation requires a base workflow that calls a local reusable workflow, and bypasses the intended separation between trusted base code and untrusted fork code.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-73800","source_modified_at":"2026-10-18T13:33:34.382Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Gitea","vendor":"Gitea","versions":[{"lessThan":"1.27.2","status":"affected","version":"1.19.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r9ch-mqjm-g67v","source_modified_at":"2026-08-14T16:34:28Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"","name":"gitea/gitea"},"range":">= 1.19.0"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-73800","source_modified_at":"2026-10-18T13:33:34.382Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Gitea","ecosystem":null},"version":"1.27.2","basis":"first unaffected version stated in the CVE record"},{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r9ch-mqjm-g67v","source_modified_at":"2026-08-14T16:34:28Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"","name":"gitea/gitea"},"version":"1.27.2"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00535,"percentile":0.44379,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:37:49.783Z","modified_at":"2026-10-18T13:33:34.382Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-73800","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-18T13:33:34.382Z"},{"source":"GitHub Advisory Database","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r9ch-mqjm-g67v","fetched_at":"2026-10-23T19:58:35.668311Z","source_modified_at":"2026-08-14T16:34:28Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-73800","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-r9ch-mqjm-g67v","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-1.27.2/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/38886","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/38897","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","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":"2026-10-18T13:33:30.814752Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-18T13:33:34.382Z","content_hash":"a3e09f8c61c5bf50e677db8ed4b538387281c500f855206d27f172d92789f6c0"}}
