{"schema":"threatline.record/2","record":{"id":"CVE-2026-96580","aliases":["GHSA-p3rv-cr5f-9gjh"],"summary":"Gitea Actions memory exhaustion through large static matrices","details":"Gitea expanded a workflow's static `strategy.matrix` into its full Cartesian product without a size limit when creating a run, before the fork pull request approval gate applied. A user who can open a pull request from a fork could submit a small workflow file whose matrix expands to a very large number of jobs, consuming server memory and potentially terminating the Gitea process. No runner is required. Static matrices above 256 combinations are now rejected before expansion.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-96580","source_modified_at":"2026-10-07T20:09:31.410Z","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"},{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-p3rv-cr5f-9gjh","source_modified_at":"2026-10-06T19:16:29Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"go","name":"gitea.dev"},"range":"<= 1.27.3"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-p3rv-cr5f-9gjh","source_modified_at":"2026-10-06T19:16:29Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"go","name":"gitea.dev"},"version":"28.0.0"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0035,"percentile":0.27484,"score_date":"2026-10-23"},"published_at":"2026-10-06T19:25:33.619Z","modified_at":"2026-10-07T20:09:31.410Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-96580","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T20:09:31.410Z"},{"source":"GitHub Advisory Database","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-p3rv-cr5f-9gjh","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-06T19:16:29Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-96580","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-p3rv-cr5f-9gjh","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39295","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":"yes","technical_impact":"partial","assessed_at":"2026-10-07T20:09:08.500896Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-07T20:09:31.410Z","content_hash":"312f50f66cc4568fe56a2c403ff850c79d269cf1d2d305e00049e5ef99d0ce9e"}}
