What is CVE-2022-4539?

The Web Application Firewall plugin for WordPress is susceptible to IP Address Spoofing due to insufficient filtering of the IP Address information utilized for logging and enforcing login restrictions. Attackers can exploit this vulnerability by modifying the X-Forwarded-For header to present a falsified IP Address.
