      "value": "The Social Icons Widget & Block by WPZOOM plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check in the add_menu_item() method hooked to admin_menu in all versions up to, and including, 4.5.8. This is due to the method performing wp_insert_post() and update_post_meta() calls to create a sharing configuration without verifying the current user has administrator-level capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger the creation of a published wpzoom-sharing configuration post with default sharing button settings, which causes social sharing buttons to be automatically injected into all post content on the frontend via the the_content filter."

Esto se debe a que el método realiza llamadas a wp_insert_post() y update_post_meta() para crear una configuración de compartición sin verificar que el usuario actual tenga capacidades de nivel de administrador. Esto hace posible que atacantes autenticados, con acceso de nivel de Suscriptor y superior, activen la creación de una publicación de configuración de compartición wpzoom publicada con la configuración predeterminada de los botones de compartición, lo que provoca que los botones de compartición social se inyecten automáticamente en todo el contenido de las publicaciones en el frontend a través del filtro the_content."
