Advisory
Source description from Wordfence Intelligence, credited to Usama Arshad.
The wpForo Forum plugin for WordPress is vulnerable to Denial of Service in versions 3.0.0 through 3.1.5. This is due to trust in attacker-controlled HTTP headers (HTTP_CF_CONNECTING_IP, HTTP_X_FORWARDED_FOR) over REMOTE_ADDR for IP-based rate limiting in the get_client_ip() function. This makes it possible for unauthenticated attackers to exhaust the site owner's metered AI credits by repeatedly spoofing the IP address header used to key per-visitor rate limits, bypassing the restriction entirely.
