express is vulnerable to Open Redirect. The vulnerability is due to improper handling of user-provided URLs during redirection in Express.js, which performs encoding using the encodeurl library before passing it to the ‘location’ header. It allows bypass of an improperly implemented allow lists and leads to an Open Redirect vulnerability.
