CVE-2021-3647 (opens in a new tab)How to fix?
Upgrade org.webjars.npm:urijs to version 1.19.11 or higher.
Overview
org.webjars.npm: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"
