Advisories for Npm/Dompurify package

It has been discovered that malicious HTML using special nesting techniques can bypass the depth checking added to DOMPurify in recent releases. It was also possible to use Prototype Pollution to weaken the depth check. This renders dompurify unable to avoid XSS attack. Fixed by https://github.com/cure53/DOMPurify/commit/1e520262bf4c66b5efda49e2316d6d1246ca7b21 (3.x branch) and https://github.com/cure53/DOMPurify/commit/26e1d69ca7f769f5c558619d644d90dd8bf26ebc (2.x branch).

DOMPurify before 1.0.11 allows reverse tabnabbing in demos/hooks-target-blank-demo.html because links lack a 'rel="noopener noreferrer"' attribute.

Cure53 DOMPurify allows mutation XSS. This occurs because a serialize-parse roundtrip does not necessarily return the original DOM tree, and a namespace can change from HTML to MathML, as demonstrated by nesting of FORM elements.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in dompurify.

DOMPurify allows XSS because of innerHTML mutation XSS (mXSS) for an SVG element or a MATH element, as demonstrated by Chrome and Safari.
