medium Tenable Self-Hosted Container Security Plugin ID 439742

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - DOMPurify before 3.3.2 contains a prototype pollution vulnerability in USE_PROFILES mode that allows
 attackers to bypass attribute filtering by polluting Array.prototype properties. Attackers can set
 Array.prototype properties like onclick to true, causing DOMPurify to accept event handlers as allowlisted
