CWE-79 Open this link in a new tab

How to fix?

Upgrade dompurify to version 0.3 or higher.


dompurify is a DOM-only XSS sanitizer for HTML, MathML and SVG. Affected versions of the package are vulnerable to Cross-site Scripting (XSS) and DOM Clobbering due to Insecure Defaults. The default configuration allowed DOM Clobbering when used by a sanitized website. The default was changed to pevent such situations.
