Upgrade node to version 22.23.4, 24.22.1, 26.12.1 or higher.
Overview
node is a JavaScript runtime built on Chrome's V8 JavaScript engine.
Affected versions of this package are vulnerable to HTTP Request Smuggling via free-socket reuse in the HTTP Agent. A remote HTTP peer can send response bytes that reach an idle keep-alive socket’s OS buffer before the event loop polls; the Agent may then reuse that socket and parse those bytes as the response to a later request, causing the client application to process attacker-controlled response data unrelated to that request.
