Vulnearability Report of the New Jersey official site
Potential XSS vulnerability when appending HTML containing option elements.
Passing HTML containing <option> elements from untrusted sources - even after sanitizing them - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.
This problem is patched in jQuery 3.5.0; Therefore, it would only be necessary to update it.
To fix this bug without updating it, we can use DOMPurify with its SAFE_FOR_JQUERY option to sanitize the HTML string before passing it to a jQuery method.
At least jQuery 1.12/2.2 or later is required to apply this workaround.
