Title: DOMPurify Improper Neutralization of Input During Web Page Generation (Cross-site Scripting) Vulnerability
Overview:

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.
