- Summary
- Express.js Open Redirect in malformed URLs
- 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 <code>encodeurl</code> on the contents before passing it to the
locationheader. 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 isres.location()but this is also called from withinres.redirect(). The vulnerability is fixed in 4.19.2 and 5.0.0-beta.3. - References
