CVE-2026-16067 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
