CVE-2024-29041
Impact
Versions of Express.js prior to 4.19.2 and pre-release alpha and beta versions before 5.0.0-beta.3 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
encodeurlon the contents before passing it to thelocationheader. 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 withinres.redirect().Patches
expressjs/express@0867302
expressjs/express@0b74695
An initial fix went out with
express@4.19.0, we then patched a feature regression in4.19.1and added improved handling for the bypass in4.19.2.Workarounds
The fix for this involves pre-parsing the url string with either
require('node:url').parseornew URL. These are steps you can take on your own before passing the user input string tores.locationorres.redirect.Resources

CVE-2024-43796
Impact
In express <4.20.0, passing untrusted user input - even after sanitizing it - to
response.redirect()may execute untrusted codePatches
this issue is patched in express 4.20.0
Workarounds
users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist
Details
successful exploitation of this vector requires the following:
