The The Ultimate WordPress Toolkit – WP Extended plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.0.8 via the download_user_ajax function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract sensitive data including usernames, hashed passwords, and emails.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
