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.","state":0,"publishedAt":"2026-10-06T19:25:33.619+00:00","modifiedAt":"2026-10-07T20:09:31.41+00:00","affected":[{"ecosystem":"Vendor product","name":"gitea.dev","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Gitea\",\n                    \"product\": \"Gitea\",\n                    \"packageName\": \"gitea.dev\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.27.3\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/go-gitea/gitea/security/advisories/GHSA-p3rv-cr5f-9gjh","https://github.com/go-gitea/gitea/pull/39295","https://blog.gitea.com/release-of-28.0.0/","https://github.com/go-gitea/gitea/releases/tag/v28.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96580","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96580","identifiers":["CVE-2026-96580"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
