[Security] Bump dompurify from 1.0.1 to 2.0.3

[dependabot-preview]

Bumps dompurify from 1.0.1 to 2.0.3. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Cross-Site Scripting in dompurify DOMPurify before 2.0.1 allows XSS because of innerHTML mutation XSS (mXSS) for an SVG element or a MATH element, as demonstrated by Chrome and Safari.

Affected versions: < 2.0.3

Release notes

Sourced from dompurify's releases.

DOMPurify 2.0.3

• Fixed another mXSS variation affecting Chrome, Safari and Edge relating to HTML templates
• Fixed a bug in the config parser leading to unexpected results

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

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
