net/http: insufficient sanitization of Host header

The HTTP/1 client did not fully validate the contents of the Host header.
A maliciously crafted Host header could inject additional headers or entire
requests. The HTTP/1 client now refuses to send requests containing an
invalid Request.Host or Request.URL.Host value.

Thanks to Bartek Nowotarski for reporting this issue.

Includes security fixes for [CVE-2023-29406 ][1] and Go issue https://go.dev/issue/60374
