wpDiscuz before 7.6.47 contains an IP spoofing vulnerability in the getIP() function that allows attackers to bypass IP-based rate limiting and ban enforcement by trusting untrusted HTTP headers. Attackers can set HTTP_CLIENT_IP or HTTP_X_FORWARDED_FOR headers to spoof their IP address and circumvent security controls.
