DOMPurify 2.0.2

Following the release of DOMPurify 2.0.1, a more thorough internal audit against Blink-based mXSS bugs was conducted. Several mXSS variations, spotted by @masatokinugawa were addressed and fixed. The fixes were reviewed and so far no new bypasses could be spotted.

This release manages to find what is believed to be a more holistic way to prevent mXSS bugs, specifically coming from HTML attributes and tags nested inside SVG and MathML.

Further, this release also addresses a DoS problem caused by sanitization of HTML tables when configured with potentially conflicting configuration settings.

DOMPurify 2.0.1

• Fixed a bypass affecting latest Chrome, caused by a newly discovered Chrome mXSS vulnerability
• Added tests to cover implemented fixes

Credits go to Michał Bentkowski (@securityMB) of Securitum who spotted the bug in Chrome, turned it into a DOMPurify bypass, reported and helped verifying the fix. 🙇
