CVE-2023-30589

The llhttp parser in the http module in Node v20.2.0 does not strictly use
the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request
Smuggling (HRS). The CR character (without LF) is sufficient to delimit
HTTP header fields in the llhttp parser. According to RFC7230 section 3,
only the CRLF sequence should delimit each header-field. This impacts all
Node.js active versions: v16, v18, and, v20
