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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":220342,"id":"CVE-2026-66874","ts":1791996229127,"field":"cvss","old":null,"new":"6.5"},{"seq":220341,"id":"CVE-2026-66874","ts":1791996229127,"field":"severity","old":"none","new":"medium"}]}
