The Free Booking Plugin for Hotels, Restaurants and Car Rentals – eaSYNC Booking plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.3.21 via the 'view_request_details' due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to view the details of any booking request. The vulnerability was partially patched in versions 1.3.18 and 1.3.21.
