CVE-2026-37604

What it is

pH7Software pH7Builder (pH7 Social Dating CMS) through 18.2.0 resolves the client IP address in _protected/framework/Ip/Ip.class.php from the HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR headers without verifying the request comes from a trusted proxy. Because the admin login attempt counter and lockout are keyed on this value, a remote unauthenticated attacker bypasses IP-based throttling by sending a different X-Forwarded-For value per request
