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.
AnalysisAI
The Gutenberg Blocks with AI by Kadence WP plugin for WordPress fails to properly validate the upload_files capability in its AJAX image import function, allowing authenticated contributors to upload arbitrary images to the Media Library despite lacking file upload permissions. This authorization bypass affects all versions up to 3.6.1 and requires only basic user authentication with no user interaction. An attacker with contributor-level access can exploit this to upload malicious image files that could be leveraged for further attacks.
