Does this matter?

Lower severity and a low EPSS score (1.13%). Track it; it rarely justifies an emergency change on its own.

Description

Undici is an HTTP/1.1 client for Node.js. Starting with version 2.0.0 and prior to version 5.19.1, the undici library does not protect `host` HTTP header from CRLF injection vulnerabilities. This issue is patched in Undici v5.19.1. As a workaround, sanitize the `headers.host` string before passing to undici.
