Name of the Vulnerable Software and Affected Versions
justhtml versions prior to 3.11.0
Description
A cross-site scripting issue exists where the default sanitizer fails to remove event handlers within selectedcontent projections. This allows attackers to inject SVG or MathML elements containing event handlers, which are then cloned and reinserted into the output without proper sanitization, leading to stored or reflected XSS attacks.
Recommendations
Update to version 3.11.0 or later.
