## Description

The Booking Package plugin for WordPress is vulnerable to unauthorized access via the 'setting', 'updateMemberSetting', 'resetSubscription' and 'deleteCalendarAccount' modes of its admin AJAX handler in all versions up to, and including, 1.7.33, due to the handler allowing every mode to any user with the edit_others_posts capability or the plugin's Booking Package Editor role, without the manager-level capability check these modes need. This makes it possible for authenticated attackers with Editor-level access or the Booking Package Editor role to change the plugin's general and member settings, reset the plugin's subscription data and delete calendar accounts.
