 "title": "Booking Calendar Contact Form <= 1.2.67 - Authenticated (Subscriber+) Missing Authorization to Arbitrary Booking Deletion",
 "description": "The Booking Calendar Contact Form plugin for WordPress is vulnerable to unauthorized deletion of data via the bookings list delete actions ('ld', 'delmark' and 'del=all' parameters) in all versions up to, and including, 1.2.67, due to the delete handlers running before the check that the current user is an administrator or the owner of the calendar. The plugin's admin page only requires the 'read' capability, and the required 'uname_bccf' nonce is printed on it for every user. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete any booking, or all bookings on the site.",
