Hydra Booking <= 1.2.1 - Authenticated (Custom+) Insecure Direct Object Reference to Sensitive Information Exposure via 'booking_id' Parameter

Affected versions: *-1.2.1

Vulnerability type: CWE-639 Authorization Bypass Through User-Controlled Key

Affected software, patched versions and attribution

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.

Hydra Booking – All in One Appointment Booking System | Appointment Scheduling, Booking Calendar & WooCommerce Bookings <= 1.1.27 - Missing Payment Verification to Unauthenticated Payment Bypass

Affected versions: *-1.1.27

Vulnerability type: CWE-602 Client-Side Enforcement of Server-Side Security

Affected software, patched versions and attribution

The Hydra Booking — Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to missing payment verification to unauthenticated payment bypass in all versions up to, and including, 1.1.27. This is due to the plugin accepting client-controlled payment confirmation data in the tfhb_meeting_paypal_payment_confirmation_callback function without server-side verification with PayPal's API. This makes it possible for unauthenticated attackers to bypass payment requirements and confirm bookings as paid without any actual payment transaction occurring.

Hydra Booking – All in One Appointment Booking System | Appointment Scheduling, Booking Calendar & WooCommerce Bookings <= 1.1.27 - Unauthenticated Arbitrary Booking Cancellation via Weak Hash Generation

Affected versions: *-1.1.27

Vulnerability type: CWE-330 Use of Insufficiently Random Values

Affected software, patched versions and attribution

The Hydra Booking — Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to unauthorized booking cancellation in all versions up to, and including, 1.1.27. This is due to the plugin's "tfhb_meeting_form_submit_callback" function using insufficiently random values to generate booking cancellation tokens, combined with a globally shared nonce. This makes it possible for unauthenticated attackers to cancel arbitrary bookings via brute force attacks against the tfhb_meeting_form_cencel AJAX endpoint.
