CVE-2023-30589

Public on 2023-06-23
Modified on 2024-02-09
Description
The llhttp parser in the http module in Node.js 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 vulnerability impacts all Node.js active versions: v16, v18, and, v20.
