Event Booking Manager for WooCommerce (Pro) < 5.0.3 - Unauthenticated Payment Bypass via Client-Controlled Ticket Price

Published Aug 6, 2026 · Updated Aug 7, 2026 · Assigned by WPScan

Description

The Event Booking Manager for WooCommerce (Pro) WordPress plugin before 5.0.3 does not validate the ticket price on the server during its native (non-WooCommerce) checkout, trusting the per-ticket price supplied by the client instead of re-deriving the event's configured price. This allows unauthenticated users to book paid event tickets for free, obtaining completed bookings and valid tickets at no cost.
