[Security] Bump dompurify from 2.0.15 to 2.2.8 #835

Closed dependabot-preview[bot] closed 3 years ago

dependabot-preview[bot] commented 3 years ago

Bumps dompurify from 2.0.15 to 2.2.8. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Cross-site Scripting in dompurify 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.

Affected versions: < 2.0.17
