NVD Description

Note: Versions mentioned in the description apply only to the upstream node-dompurify package and not the node-dompurify package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. In 3.4.4, DOMPurify allowed selectedcontent by default, allowing browsers to re-clone an XSS payload after sanitization so that unsanitized markup inside <selectedcontent> is returned. This issue is fixed in version 3.4.5.
