Vulnerabilidad · Publicado 25/09/2026
El plugin Bookly para WordPress (versiones hasta 28.2) contiene una vulnerabilidad de Referencia Directa a Objetos (IDOR) en acciones AJAX que permite a atacantes acceder y manipular datos de reservas, sesiones y órdenes sin autenticación. Afecta directamente a negocios de servicios en LATAM que usan este plugin para gestionar citas y pagos online, exponiendo información de clientes y transacciones.
The Bookly plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 28.2 via the 'bookly_get_form_id', 'bookly_render_complete', 'bookly_add_to_calendar' and 'bookly_rollback_order' AJAX actions. This is due to the 'bookly_get_form_id' handler blindly storing the attacker-controlled 'order_id' from the submitted form_data into a new booking session, which the 'bookly_render_complete' handler then trusts to look up and return the corresponding Order's secret token without verifying that the current session created that order. This makes it possible for unauthenticated attackers to enumerate sequential order IDs, disclose other customers' order tokens, retrieve calendar/appointment information via 'bookly_add_to_calendar' and permanently delete arbitrary non-completed bookings via 'bookly_rollback_order', which cascade-deletes the customer_appointment and (when no other customers are attached) the underlying appointment.
