How to fix?

Upgrade url-parse to version 1.5.8 or higher.

Overview

url-parse is a Small footprint URL parser that works seamlessly across Node.js and browser environments.

Affected versions of this package are vulnerable to Authorization Bypass via the hostname field of a parsed URL, because "url-parse" is unable to find the correct hostname when no port number is provided in the URL.

PoC:

var Url = require('url-parse');
var PAYLOAD = "http://example.com:";

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: '',
  origin: 'http://example.com:',
  href: 'http://example.com:/'
}
