How to fix?

Upgrade urijs to version 1.19.7 or higher.

Overview

urijs is a Javascript library for working with URLs.

Affected versions of this package are vulnerable to Open Redirect. It mishandles certain uses of backslash such as https:/\ and interprets the URI as a relative path. Browsers usually accept backslashes after the protocol, and treat it as a normal slash.

PoC

var URI = require('urijs');
var url = new URI("https:/\/\/\www.google.com");
console.log(url);  // Which will return -->  path: "/www.google.com"
