Technical details

Reflected cross-site scripting (XSS) vulnerability in the 'field_attr[required]' parameter due to insufficient input sanitization and output escaping. The wpuf_get_child_cat AJAX action nonce check provides inadequate protection because the wpuf_nonce is publicly localized to all anonymous visitors of pages with WPUF shortcodes, allowing unauthenticated attackers to harvest and reuse it. Attack vector is network-based requiring user interaction (clicking a malicious link).
