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.</p> <p><strong>Affected:</strong> cure53 DOMPurify</p> <p>DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG.
