If you're relying on blocking access to localhost using the default 0.0.0.0 filter this can be bypassed using other registered loopback devices (like 127.0.0.2 - 127.127.127.127)
You can block this bypass by manually adding the 127.0.0.0/8 CIDR range which will block access to any 127.X.X.X ip instead of just 127.0.0.1.
