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

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

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.

Spin Wheel <= 2.1.0 - Unauthenticated Client-Side Prize Manipulation via 'prize_index' Parameter

The Spin Wheel plugin for WordPress is vulnerable to client-side prize manipulation in all versions up to, and including, 2.1.0. This is due to the plugin trusting client-supplied prize selection data without server-side validation or randomization. This makes it possible for unauthenticated attackers to manipulate which prize they win by modifying the 'prize_index' parameter sent to the server, allowing them to always select the most valuable prizes.
