How to fix?

Upgrade express-openid-connect to version 2.7.2 or higher.

Overview

express-openid-connect is an Express JS middleware implementing sign on for Express web apps using OpenID Connect.

Affected versions of this package are vulnerable to Open Redirect when the middleware is applied to a catch all route.

If all routes under example.com are protected with the requiresAuth middleware, a visit to http://example.com//google.com will be redirected to google.com after login because the original url reported by the Express framework is not properly sanitised.
