The Easy Appointments plugin for WordPress is vulnerable to unauthorized modification of data due to insufficient user validation on the ajax_cancel_appointment() function in all versions up to, and including, 3.11.18. This makes it possible for unauthenticated attackers to cancel other users orders.
