A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and denial of service (DoS).

The issue can cause CPU and network bandwidth exhaustion, bypassing standard safeguards like timeouts and body size limits.
