wpForo Forum 3.0.0 - 3.1.5 - Unauthenticated AI Credit Exhaustion
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.
