      "value": "The ProfilePress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.16.11. This is due to missing ownership validation on the change_plan_sub_id parameter in the process_checkout() function. The ppress_process_checkout AJAX handler accepts a user-controlled subscription ID intended for plan upgrades, loads the subscription record, and cancels/expires it without verifying the subscription belongs to the requesting user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to cancel and expire any other user's active subscription via the change_plan_sub_id parameter during checkout, causing immediate loss of paid access for victims."

      "value": "El plugin ProfilePress para WordPress es vulnerable a Referencia Directa Insegura a Objeto en todas las versiones hasta la 4.16.11, inclusive. Esto se debe a la falta de validación de propiedad en el parámetro change_plan_sub_id en la función process_checkout(). El gestor AJAX ppress_process_checkout acepta un ID de suscripción controlado por el usuario destinado a actualizaciones de plan, carga el registro de suscripción y lo cancela/expira sin verificar que la suscripción pertenezca al usuario solicitante. Esto hace posible que atacantes autenticados, con acceso de nivel Suscriptor y superior, cancelen y expiren la suscripción activa de cualquier otro usuario a través del parámetro change_plan_sub_id durante el proceso de pago, causando la pérdida inmediata del acceso de pago para las víctimas."
