In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing elements from untrusted sources - even after sanitizing it - 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.
