Overview
node is a JavaScript runtime built on Chrome's V8 JavaScript engine.
Affected versions of this package are vulnerable to HTTP Request Smuggling in the HTTP client when forwarding proxies rebuild outbound headers from the visible IncomingMessage headers while piping the original body to a reused backend connection. An attacker can manipulate HTTP request headers by sending requests with a large number of headers, causing certain headers such as Content-Length to be omitted from userland while still being used internally for HTTP message framing, potentially leading to request desynchronization.
