{"id":"CVE-2026-66874","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.","aliases":["GHSA-5xp7-r6cr-39ff"],"modified":"2026-10-15T02:47:41.309742343Z","published":"2026-10-14T14:36:06.090Z","database_specific":{"cwe_ids":["CWE-284","CWE-345","CWE-693","CWE-807"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/66xxx/CVE-2026-66874.json","cna_assigner":"Gitea"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-1.27.3/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/66xxx/CVE-2026-66874.json"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39005"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39018"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xp7-r6cr-39ff"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66874"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"last_affected":"1dac1bb2f8593d4319125fa6bca9283000a2ddc2"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"1.27.2"}]}}],"versions":["v1.27.2","v1.27.1","v1.27.0","v1.27.0-rc0","v1.28.0-dev","v1.27.0-dev","v1.26.0-dev","v1.25.0-dev","v1.24.0-dev","v1.22.0-rc1","v1.23.0-dev","v1.22.0-rc0","v1.21.0-rc0","v1.22.0-dev","v1.20.0-rc0","v1.21.0-dev","v1.20.0-dev","v1.19.0-rc0","v1.18.0-rc0","v1.19.0-dev","v1.18.0-dev","v1.17.0-dev","v1.16.0-rc1","v1.15.0-rc1","v1.16.0-dev","v1.15.0-dev","v1.14.0-dev","v1.13.0-dev","v1.12.0-dev","v1.10.5","v1.11.0-rc1","v1.10.0-rc1","v1.11.0-dev","v1.9.0-rc1","v1.10.0-dev","v1.9.0-dev","v1.7.0-dev","v1.6.0-rc1","v1.6.0-dev","v1.5.0-rc1","v1.5.0-dev","v1.1.0","v1.0.0","v0.9.99"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-66874.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
