This is due to the wpcs_send_email() function being registered on both wp_ajax_wpcs_send_email and wp_ajax_nopriv_wpcs_send_email with no nonce verification, capability check, or rate limiting, while forwarding attacker-controlled recipient, subject, and body directly to wp_mail(). This makes it possible for unauthenticated attackers to send arbitrary emails to any recipient from the site&#39;s domain, enabling spam, phishing, and abuse that can lead to the site&#39;s IP/domain being blacklisted.</p> <p><strong>Affected:</strong> quantumcloud WPBot – AI ChatBot for Live Support, Lead Generation, AI Services</p> <p>The Chatbot plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 8.5.9 via the wpcs_send_email() AJAX handler.
