Travel Engine <= 6.8.4 - Insecure Direct Object Reference to Unauthenticated Booking Details Disclosure and Modification
The Travel Engine plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 6.8.4. This is due to missing ownership check on the caller-supplied booking_id parameter in the AddToCart AJAX handler, allowing any unauthenticated user to reference arbitrary booking posts. This makes it possible for unauthenticated attackers to view or modify booking details belonging to other users by supplying an arbitrary booking ID to the wte_add_trip_to_cart AJAX action.
