Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada cure53 dompurify. Skor CVSS 3.1 6.1 (Medium) menurut github.com.

Deskripsi (NVD)

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.
