{"id":"CVE-2026-104632","summary":"Gitea fork workflow approval bypass through cancel and rerun","details":"Gitea Actions blocks the jobs of workflow runs from first-time fork pull request contributors until a maintainer approves the run. The rerun path only required a run to be finished and built the new attempt's jobs without considering the pending approval, so when a user with Actions write access cancelled a run that was awaiting approval and then re-ran it, the new jobs were created as waiting rather than blocked while the run still recorded that approval was required. Cancelling and re-running stale fork checks is a routine action that does not involve the approval control, so where Actions is enabled and a matching runner is registered, workflow code taken from the fork pull request head could run on the repository's runners without an explicit approval.","aliases":["GHSA-pvjf-7jrm-6w9g"],"modified":"2026-10-07T10:46:54.446982773Z","published":"2026-10-06T19:22:04.308Z","database_specific":{"cna_assigner":"Gitea","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104632.json"},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-28.0.0/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104632.json"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39399"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v28.0.0"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-pvjf-7jrm-6w9g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104632"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"0"},{"last_affected":"146cc3eec57174711eac0e0a0c7b38670c6e3922"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.27.3"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.27.3","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-2026-104632.json"}}],"schema_version":"1.9.0"}
