Vulnerability Details

Express.js minimalist web framework for node. Versions of Express.js prior to 4.19.0 and all pre-release alpha and beta versions of 5.0 are affected by an open redirect vulnerability using malformed URLs. When a user of Express performs a redirect using a user-provided URL Express performs an encode [using `encodeurl`](https://github.com/pillarjs/encodeurl) on the contents before passing it to the `location` header. This can cause malformed URLs to be evaluated in unexpected ways by common redirect allow list implementations in Express applications, leading to an Open Redirect via bypass of a properly implemented allow list. The main method impacted is `res.location()` but this is also called from within `res.redirect()`. The vulnerability is fixed in 4.19.2 and 5.0.0-beta.3.

Matched on "open redirect"

What is this? (2min video)

This vulnerability refers to the ability of an attacker to arbitrarily perform a redirection (external) or forward (internal) against the system. It arises due to insufficient validation or sanitisation of inputs used to perform a redirect or forward and may result in privilege escalation (in the case of a forward) or may be used to launch phishing attacks against users (in the case of redirects).
