The host is installed with Node.js 18.x before 18.19.1, 20.x before 20.11.1, or 21.x before 21.6.2 and is prone to a denial of service vulnerability. A flaw is present in the application which fails to handle a specially crafted HTTP request with chunked encoding. Successful exploitation could allow an attacker to cause resource exhaustion and denial of service (DoS) leading to CPU and network bandwidth exhaustion, bypassing standard safeguards like timeouts and body size limits.
