Description
The Appointment Booking Plugin for WordPress before version 5.7.6 contains a cross-site scripting (XSS) vulnerability. This flaw arises because several booking-form step content settings are not properly escaped before being rendered on the public booking form. High-privilege users, such as administrators, can exploit this to inject JavaScript code that executes in the browsers of visitors who load the form. On multisite installations where administrators lack the unfiltered_html capability, this vulnerability allows crossing a privilege boundary to unauthenticated visitors.
