Summary
Nodejs ‘undici’ vulnerable to CRLF Injection via Content-Type
Details

Impact

=< undici@5.8.0 users are vulnerable to CRLF Injection on headers when using unsanitized input as request headers, more specifically, inside the content-type header.

Example:

import { request } from 'undici'

const unsanitizedContentTypeInput =  'application/json\r\n\r\nGET /foo2 HTTP/1.1'

await request('http://localhost:3000, {
    method: 'GET',
    headers: {
      'content-type': unsanitizedContentTypeInput
    },
})

The above snippet will perform two requests in a single request API call:

1) http://localhost:3000/ 2) http://localhost:3000/foo2

Patches

This issue was patched in Undici v5.8.1

Workarounds

Sanitize input when sending content-type headers using user input.
