- Summary
- DOMPurify XSS via `selectedcontent` re-clone
- Details
-
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 is returned. This issue is fixed in version 3.4.5.
