CVE-2022-4746: 
WordPress vulnerability analysis and mitigation

The FluentAuth WordPress plugin before version 1.0.2 contains a security vulnerability identified as CVE-2022-4746. The vulnerability was discovered and publicly disclosed on December 27, 2022. This security issue affects the IP-based blocking functionality of the FluentAuth WordPress plugin (WPScan).

The vulnerability stems from a design flaw where the plugin prioritizes obtaining visitor IP addresses from HTTP headers (HTTPXREALIP, HTTPXFORWARDEDFOR, HTTPCFCONNECTINGIP, or HTTPCLIENTIP) over PHP's REMOTEADDR. This implementation weakness is classified as CWE-290, relating to authentication bypass through spoofing (NVD CNA Status).

The vulnerability allows malicious actors to bypass IP-based blocks implemented by the plugin. By manipulating specific HTTP headers, attackers can spoof their IP address and circumvent the security measures intended to restrict access based on IP addresses (WPScan).

The vulnerability has been patched in FluentAuth version 1.0.2. Users are strongly advised to update their FluentAuth WordPress plugin to this version or later to address the security issue (WPScan).
