Description

A flaw was found in undici, a Node.js HTTP/1.1 client. This vulnerability allows a remote attacker to inject malicious data into HTTP headers or prematurely end HTTP requests by sending specially crafted input to the `upgrade` option of `client.request()`. This is possible because undici does not properly validate input for invalid header characters, which could lead to unauthorized information disclosure or bypassing of security controls.
