The Download Manager plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'reviewUserStatus' function in all versions up to, and including, 3.3.49. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve sensitive information for any user on the site including email addresses, display names, and registration dates.
