{"id":"BIT-gitea-2026-104626","summary":"Gitea fork workflow job revival through later approval","details":"A user who can open a fork pull request can place workflow content with a shared run-level concurrency group into a Gitea Actions run that is awaiting approval. When a later run in that group cancels the blocked job, the run becomes terminal while still marked as needing approval. If a maintainer later approves the run, Gitea passed the already-cancelled job back through concurrency preparation, set it to waiting, and made it claimable by a matching runner, executing fork-controlled workflow code. Exploitation requires the maintainer's later approval action, Actions to be enabled, and a runner that accepts the repository's jobs.","aliases":["CVE-2026-104626","GHSA-93pj-3x56-5gc2"],"modified":"2026-10-14T11:11:12.735691247Z","published":"2026-10-14T08:42:37.770Z","database_specific":{"cpes":["cpe:2.3:a:gitea:gitea:*:*:*:*:*:*:*:*"],"severity":"High"},"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-93pj-3x56-5gc2"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104626"}],"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-2026-104626.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"}
