 "title": "AI Engine <= 3.8.7 - Unauthenticated IP Address Spoofing via Forwarded HTTP Headers",
 "description": "The AI Engine plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 3.8.7, due to the get_ip_address() function trusting client-supplied headers such as X-Forwarded-For, Client-IP and X-Real-IP before REMOTE_ADDR, without checking that the request came through a trusted proxy. This makes it possible for unauthenticated attackers to present any IP address they choose, and so get around IP-based restrictions such as the Banned IPs setting and per-IP rate limits, and to falsify the IP address recorded with discussions.",
