How to fix?

Upgrade undici to version 5.26.2 or higher.

Overview

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Information Exposure during the Cookie headers handling process. An attacker can potentially leak sensitive information to a third-party site or a malicious actor who can control the redirection target (i.e., an open redirector) by exploiting the disconnect between the spec's assumptions and the implementation of fetch.

Note:

This is only exploitable if the attacker can control the redirection target.
