The wiseCampaign – WooCommerce Conversions Made Easy plugin for WordPress is vulnerable to unauthorized modification and disclosure of data due to every one of its REST API endpoints being registered with `permission_callback => '__return_true'` in all versions up to, and including, 1.1.16. This makes it possible for unauthenticated attackers to read and modify the plugin's banner, stockbar, and core settings — including saving/updating banner records, toggling stockbar/feature flags, changing the active banner, and uploading background-image files via wp_handle_upload() — without any nonce or capability check.
