Open Redirect

express is a minimalist web framework.

Affected versions of this package are vulnerable to Open Redirect due to the implementation of URL encoding using encodeurl before passing it to the location header. This can lead to unexpected evaluations of malformed URLs by common redirect allow list implementations in applications, allowing an attacker to bypass a properly implemented allow list and redirect users to malicious sites.

How to fix Open Redirect?

Upgrade express to version 4.19.2, 5.0.0-beta.3 or higher.

Cross-site Scripting (XSS)

express is a minimalist web framework.

Affected versions of this package do not enforce the user's browser to set a specific charset in the content-type header while displaying 400 level response messages. This could be used by remote attackers to perform a cross-site scripting attack, by using non-standard encodings like UTF-7.
