GHSA-V8FW-85R8-5M23 Deno: Node TCPWrap numeric hostname aliases bypass --deny-net resolved-IP deny checks

Summary Deno's network permission model is designed so that --deny-net rules apply to the resolved IP address of a destination, not just the literal string supplied by the caller. That means --deny-net=127.0.0.1 or --deny-net=127.0.0.0/8 is expected to block any attempt to reach loopback,...
