CVE-2026-16067: Unknown Event Booking Manager For Woocommerce Pro

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
