A user who can open a pull request from a fork could submit a small workflow file whose matrix expands to a very large number of jobs, consuming server memory and potentially terminating the Gitea process. No runner is required. Static matrices above 256 combinations are now rejected before expansion.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
