## Description

The Bus Ticket Booking with Seat Reservation plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'booking_id' parameter of the standalone (Custom Payment) checkout and booking confirmation pages in all versions up to, and including, 5.8.8, due to missing ownership validation on the user-controlled booking ID. This makes it possible for unauthenticated attackers to enumerate booking IDs and view other customers' booking details, including route, travel date and time, bus, seat numbers, ticket types, extra services, applied coupon and amounts paid or due.
