No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The WP Ghost (Hide My WP Ghost) WordPress plugin before 7.0.05 does not verify that client IP information comes from a trusted proxy before trusting attacker-controllable HTTP headers, allowing unauthenticated attackers to spoof their IP address to bypass the WP Ghost (Hide My WP Ghost) WordPress plugin before 7.0.05's own brute-force protection and to downgrade its firewall by matching a hardcoded whitelisted IP range.
