The Hydra Booking – Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 1.2.1 via the /wp-json/hydra-booking/v1/booking/details/{id} REST endpoint. This is due to the getBookingDetails() callback only enforcing the tfhb_manage_options capability via tfhb_manage_options_permission(), without verifying that the requested booking belongs to the currently authenticated host (the lookup in getBookingDetailsData() filters solely on the booking id supplied in the URL). This makes it possible for authenticated attackers, with Hydra Host-level access and above (a role created by the plugin which grants tfhb_manage_options), to view sensitive booking records belonging to other hosts, including attendee names, emails, phone numbers, addresses, meeting details, payment method and status, transaction history, and internal notes by iterating booking IDs.

The advisory is shared at wordfence.com. The identification of this vulnerability is CVE-2026-12433 since 06/16/2026. The exploitation is known to be easy. The attack may be initiated remotely. The exploitation requires an enhanced level of successful authentication. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/09/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
