Overview

Affected versions of this package are vulnerable to Denial of Service (DoS) due to improper validation of the value passed to the n parameter in the /v2/_catalog endpoint. Exploiting this vulnerability is possible by sending a crafted malicious request to the /v2/_catalog API endpoint, which results in an allocation of a massive string array and excessive use of memory.
