The MotoPress Appointment Booking WordPress plugin before 2.4.8 does not perform an authorization or ownership check when handling a user-supplied booking identifier on an unauthenticated endpoint, allowing unauthenticated attackers to permanently delete other users' reservations. This is an incomplete fix of CVE-2026-9180: the deletion remains reachable on sites using payment confirmation, confirmed through version 2.4.7.
