CVE-2023-2253 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. A flaw was found in the `/v2/_catalog` endpoint in distribution/distribution, which accepts a parameter to control the maximum number of records returned (query string: `n`). This vulnerability allows a malicious user to submit an unreasonably large value for `n,` causing the allocation of a massive string array, possibly causing a denial of service through excessive use of memory.. EPSS estimates a 0.94% chance of exploitation in the next 30 days.
