A separate run sharing a job-level concurrency group can cancel a pending job and cause its blocked sibling jobs to be re-emitted and dispatched without approval. This allows unreviewed workflow code to execute on self-hosted runners; fork secrets remain withheld and the run token remains read-only.\nhttps://www.cve.org/CVERecord?id=CVE-2026-66877https://github.com/go-gitea/gitea/security/advisories/GHSA-v2w8-m4gr-qj65https://blog.gitea.com/release-of-1.27.3/https://github.com/go-gitea/gitea/pull/39005https://github.com/go-gitea/gitea/pull/39018https://github.com/go-gitea/gitea/releases/tag/v1.27.3#gitea #Gitea#CVE_2026_66877#bot", "url": "https://infosec.exchange/users/cve/statuses/117441029671314963"}, {"timestamp": "2026-10-15T03:56:53.515Z", "date_only": false, "value": "2026-10-15T03:56:53.515Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-66877", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-15T03:56:53.515Z", "date_only": false, "value": "2026-10-15T03:56:53.515Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-66877", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-15T04:18:25.113Z", "date_only": false, "value": "2026-10-15T04:18:25.113", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-66877", "record": "FKIE_CVE-2026-66877", "field": "lastModified"}]}
