Impact
It is possible to inject CRLF sequences into request headers in Undici.
const undici = require('undici')
const response = undici.request("http://127.0.0.1:1000", {
headers: {'a': "\r\nb"}
})
The same applies to path and method
Patches
Update to v5.8.0
Workarounds
Sanitize all HTTP headers from untrusted sources to eliminate \r\n.
