Repository initialization splits the field into template names, repeatedly reads the referenced templates, and buffers their contents in memory. An attacker who can create repositories can submit an oversized value to amplify template reads and memory use, impairing availability.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":220366,"id":"CVE-2026-73130","ts":1791996233306,"field":"cvss","old":null,"new":"4.3"},{"seq":220365,"id":"CVE-2026-73130","ts":1791996233306,"field":"severity","old":"none","new":"medium"}]}
