CVE-2026-17166 — MEDIUM (4.3)

Vulnerability Description

The Event Booking Manager for WooCommerce – Sell Tickets, Event Registration, RSVP & Event Calendar plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.3.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to modify site-wide payment settings — including WooCommerce payment enablement, cart redirect behavior, login requirements for checkout, confirmation page ID, and confirmed ticket statuses — that govern how all event bookings are processed.
