      "value": "The Gutenberg Blocks with AI by Kadence WP plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.6.1. This is due to a missing capability check in the `process_image_data_ajax_callback()` function which handles the `kadence_import_process_image_data` AJAX action. The function's authorization check via `verify_ajax_call()` only validates `edit_posts` capability but fails to check for the `upload_files` capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload arbitrary images from remote URLs to the WordPress Media Library, bypassing the standard WordPress capability restriction that prevents Contributors from uploading files."

      "value": "El plugin Gutenberg Blocks with AI by Kadence WP para WordPress es vulnerable a una autorización faltante en todas las versiones hasta la 3.6.1, inclusive. Esto se debe a una verificación de capacidad faltante en la función `process_image_data_ajax_callback()` que maneja la acción AJAX `kadence_import_process_image_data`. La verificación de autorización de la función a través de `verify_ajax_call()` solo valida la capacidad `edit_posts` pero no verifica la capacidad `upload_files`. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, carguen imágenes arbitrarias desde URLs remotas a la biblioteca de medios de WordPress, eludiendo la restricción de capacidad estándar de WordPress que impide a los Colaboradores cargar archivos."
