A vulnerability was found in NodeJS due to improper validation of HTTP requests. The llhttp parser in the HTTP module in Node.js does not correctly handle header fields that are not terminated with CLRF. This issue may result in HTTP Request Smuggling. This flaw allows a remote attacker to send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

A vulnerability was found in NodeJS due to the llhttp parser in the http module not strictly using the CRLF sequence to delimit HTTP requests. This issue can lead to HTTP Request Smuggling (HRS). This flaw allows an attacker to send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers, causing web cache poisoning, and conducting XSS attacks.

An HTTP Request Smuggling (HRS) vulnerability was found in the llhttp library, used by Node.JS. Spaces as part of the header names were accepted as valid. In situations where HTTP conversations are being proxied (such as proxy, reverse-proxy, load-balancer), an attacker can use this flaw to inject arbitrary messages through the proxy. The highest threat from this vulnerability is to confidentiality and integrity.

An HTTP Request Smuggling (HRS) vulnerability was found in the llhttp library, used by Node.JS. During the parsing of chunked messages, the chunk size parameter was not validated properly. In situations where HTTP conversations are being proxied (such as proxy, reverse-proxy, load-balancer), an attacker can use this flaw to inject arbitrary messages through the proxy. The highest threat from this vulnerability is to confidentiality and integrity.
