Antispam Bee < 2.11.4 - IP Address Spoofing via get_client_ip

Description The Antispam Bee plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 2.11.3 due to use of user-supplied HTTP headers as a primary method for IP retrieval. This makes it possible for unauthenticated attackers to bypass country blocking.
