Technical details
The plugin fails to escape booking-form step content settings before rendering them on the public booking form, resulting in stored cross-site scripting (XSS). Administrators can inject arbitrary JavaScript that persists in the database and executes in the browsers of all users who visit the form. On multisite installations where administrators lack the unfiltered_html capability, unauthenticated attackers can exploit this by gaining initial admin access through other means or via misconfiguration.
