The vulnerability stems from the formatItem callback in the autocomplete widget implementation. The original code (pre-patch) concatenated raw user input from data[options.nameKey] and data[options.descKey] into HTML strings without sanitization. The patch fixes this by using jQuery.text() method to HTML-escape the description content. The function's direct handling of unescaped user input in HTML construction matches the described XSS vulnerability vector via user full names.
