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
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.
