An authenticated user with package-publish permission can submit an oversized body to a checksum endpoint despite legitimate checksum values being at most 128 bytes. This bypasses the upload quota on that path and can exhaust server memory.\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":220370,"id":"CVE-2026-73273","ts":1791996233953,"field":"cvss","old":null,"new":"4.3"},{"seq":220369,"id":"CVE-2026-73273","ts":1791996233953,"field":"severity","old":"none","new":"medium"}]}
