A fork pull request author can supply a workflow matching a required status context but deliberately prevent it from running. Because skipped statuses count as success, branch protection or organization-required workflow checks can appear satisfied without the mandated workflow executing; no runner or maintainer approval is required for this path."}],"affected":[{"vendor":"Gitea","product":"Gitea","packageName":"gitea.dev","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.27.2","versionType":"semver"}]}],"references":[{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xp7-r6cr-39ff","name":"GitHub Security Advisory GHSA-5xp7-r6cr-39ff","tags":["vendor-advisory"]},{"url":"https://blog.gitea.com/release-of-1.27.3/","name":"Gitea 1.27.3 release announcement","tags":["release-notes"]},{"url":"https://github.com/go-gitea/gitea/pull/39005","name":"Fix: go-gitea/gitea pull request #39005","tags":["patch"]},{"url":"https://github.com/go-gitea/gitea/pull/39018","name":"Fix: go-gitea/gitea pull request #39018","tags":["patch"]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","name":"go-gitea/gitea v1.27.3 release","tags":["release-notes"]}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-284","description":"CWE-284: Improper Access Control"},{"lang":"en","type":"CWE","cweId":"CWE-345","description":"CWE-345: Insufficient Verification of Data Authenticity"},{"lang":"en","type":"CWE","cweId":"CWE-693","description":"CWE-693: Protection Mechanism Failure"},{"lang":"en","type":"CWE","cweId":"CWE-807","description":"CWE-807: Reliance on Untrusted Inputs in a Security Decision"}]}],"credits":[{"lang":"en","value":"https://github.com/iabdullah215","type":"reporter"},{"lang":"en","value":"https://github.com/effabinteashfaq","type":"reporter"},{"lang":"en","value":"https://github.com/bircni","type":"remediation developer"}]},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":6.5,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-10-14T15:12:30.376099Z","id":"CVE-2026-66874","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-14T15:12:51.792Z"}}]}}
