CVE-2026-15250

The Appointment Booking Plugin WordPress plugin before 5.7.3 does not verify that the caller owns the order referenced by an order-item identifier before rendering that order's confirmation summary, letting an unauthenticated visitor retrieve any customer's name, contact details and order confirmation code by supplying a sequential order-item id.

The Appointment Booking Plugin WordPress plugin before version 5.6.5 does not verify that a backend staff user is authorized to act on the specific record targeted for deletion, allowing an authenticated user with a record-scoped staff role to irreversibly delete any order, customer, or transaction on the site, including records belonging to other staff and outside their assigned scope.

The Appointment Booking Plugin WordPress plugin before version 5.6.9 does not enforce per-record authorization on several of its AI Abilities API actions, allowing an authenticated user holding the LatePoint Agent role, normally restricted to their own records, to read and modify other agents' profile data and read other agents' bookings and associated customer details when the Abilities API feature is enabled.

The Appointment Booking Plugin for WordPress before version 5.6.3 does not validate a CSRF nonce on several state-changing actions handled by its central request dispatcher. This allows 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.
