CVE-2026-16067 - Before 5 Plugin

CVE-2026-16067

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.
