medium Tenable Cloud Security Plugin ID 443248

Description

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

 - DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Prior to 3.4.6,
 DOMPurify.sanitize(root, { IN_PLACE: true }) could preserve event-handler attributes on an attacker-
 controlled <form> root when a descendant name clobbered properties checked by _isClobbered, because
 _forceRemove no-opped on the parent-less root and _sanitizeAttributes returned early. This issue is fixed
 in version 3.4.6. (CVE-2026-49459)

Solution

Update the dompurify library and its related packages to version 3.4.6 or later.
