Summary
HtmlSanitizer vulnerable to XSS when used with contentEditable
Original description
The description as published by the source.
HtmlSanitizer is a client-side HTML Sanitizer. Versions prior to 2.0.3 have a cross-site scripting vulnerability when the sanitizer is used with a contentEditable element to set the elements innerHTML to a sanitized string produced by the package. If the code is particularly crafted to abuse the code beautifier, that runs AFTER sanitation. The issue is patched in version 2.0.3.
