Advisory

Source description from Wordfence Intelligence, credited to Bartłomiej Marek, Tomasz Swiadek.

The Activity Log plugin for WordPress is vulnerable to IP Address Spoofing in versions up to, and including, 2.8.7. This is due to insufficient restrictions on where the IP Address information is being retrieved for request logging. Unauthenticated attackers can supply the X-Forwarded-For header with with a different IP Address that will be logged instead of the users true IP address.
