The Easy Appointments plugin for WordPress has a security issue that allows unauthorized changes to be made to data. This is because the plugin does not properly check the identity of the user on the ajax_cancel_appointment() function in all versions up to 3.11.18. As a result, people who are not logged in can cancel appointments made by other users.
