CVE-2026-11866

The Appointment Booking Plugin WordPress plugin before 5.6.3 does not validate a CSRF nonce on several state-changing actions handled by its central request dispatcher, allowing attackers to perform privileged actions, such as overwriting the booking-form configuration or disconnecting the connected payment gateway, via Cross-Site Request Forgery against a logged-in administrator.
