The Malware Scanner plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 4.7.1 due to insufficient IP address validation and use of user-supplied HTTP headers as a primary method for IP retrieval. This makes it possible for unauthenticated attackers to bypass IP blocking functionality.
