Summary

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. Unauthenticated attackers can spoof their IP address to bypass the plugin's own brute-force protection and to downgrade its firewall by matching a hardcoded whitelisted IP range.

Risk Assessment

An attacker can bypass brute-force protection and weaken firewall defenses, facilitating further attacks on the site.

Recommendation

Update the WP Ghost (Hide My WP Ghost) plugin to version 7.0.05 or later.
