The WP Register Profile With Shortcode plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.6.2 via the 'rp_user_data' shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data from user meta like hashed passwords, usernames, and more.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
