CVE-2020-26870 WRITEUP MEDIUM WRITEUP
DOMPurify < 2.0.17 - Mutation Cross-Site Scripting via MathML Namespace Bypass
Cure53 DOMPurify before 2.0.17 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.
