The User Activity Log Pro plugin for WordPress is vulnerable to IP Address Spoofing in versions up to, and including, 2.3.3 due to insufficient IP address validation. This makes it possible for attackers to perform actions that are attributed to IP values that they control, rather than to the correct IP.
