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."}],"affected":[{"source":"88ee5874-cf24-4952-aea0-31affedb7ff2","affectedData":[{"vendor":"Gitea","product":"Gitea","defaultStatus":"unaffected","packageName":"code.gitea.io/gitea","versions":[{"version":"0","lessThanOrEqual":"1.27.2","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-14T00:00:00+00:00","id":"CVE-2026-66877","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","description":[{"lang":"en","value":"CWE-284"}]}],"references":[{"url":"https://blog.gitea.com/release-of-1.27.3/","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/pull/39005","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/pull/39018","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-v2w8-m4gr-qj65","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"}]}}]}
