A source that reported `max_response_items` as `0` made these loops run indefinitely and grow server memory until it was exhausted. Any user who can migrate repositories could point a migration at a server they control and cause a denial of service.\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":[]}
