suggestion: Consider handling IPv6-mapped IPv4 addresses for localhost.

Also include '::ffff:127.0.0.1' in the internal connection check to cover IPv6-mapped IPv4 localhost addresses.

Suggested change
const isInternalConnection = req.socket.remoteAddress === '127.0.0.1' || req.socket.remoteAddress === '::1';
const isInternalConnection =
req.socket.remoteAddress === '127.0.0.1' ||
req.socket.remoteAddress === '::1' ||
req.socket.remoteAddress === '::ffff:127.0.0.1';

const params = new URLSearchParams(url.search);

// Permite conexões internas do Socket.IO (EIO=4 é o Engine.IO v4)
if (params.has('EIO')) {
if (params.has('EIO') && isInternalConnection) {
return callback(null, true);
}
