      "value": "The WPAdverts – Classifieds Plugin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve internal site configuration data exposed by the classifieds-types REST endpoint, including registered post types, labels, associated taxonomies, form scheme metadata, contact options, and custom field meta keys."

Esto se debe a que el plugin no verifica correctamente que un usuario está autorizado para realizar una acción. Esto hace posible que atacantes no autenticados recuperen datos de configuración interna del sitio expuestos por el endpoint REST classifieds-types, incluyendo tipos de publicación registrados, etiquetas, taxonomías asociadas, metadatos del esquema del formulario, opciones de contacto y claves meta de campos personalizados."
