{"id":"BIT-gitea-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":["CVE-2026-104632","GHSA-pvjf-7jrm-6w9g"],"modified":"2026-10-14T11:11:03.691478038Z","published":"2026-10-14T08:42:38.952Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:gitea:gitea:*:*:*:*:*:*:*:*"]},"references":[{"type":"ARTICLE","url":"https://blog.gitea.com/release-of-28.0.0/"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39399"},{"type":"ARTICLE","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":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104632"}],"affected":[{"package":{"name":"gitea","ecosystem":"Bitnami","purl":"pkg:bitnami/gitea"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"28.0.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/gitea/BIT-gitea-2026-104632.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
