SCA: security update for dompurify (GHSA-hpcv-96wg-7vj8)

medium Tenable Self-Hosted Container Security Plugin ID 443239

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(node, { IN_PLACE: true }) accepted same-origin foreign-realm DOM nodes while follow-on
 checks used parent-realm constructors, causing instanceof checks for forms, named node maps, document
 fragments, and elements to fail and skip clobber, template-content, and shadow-DOM sanitization branches
 so executable markup could survive. This issue is fixed in version 3.4.6. (CVE-2026-49458)

Solution

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