How to fix?

Upgrade node to version 14.21.1, 16.18.1, 18.12.1, 19.0.1 or higher.

Overview

node is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Affected versions of this package are vulnerable to DNS Rebinding due to the way the IsIPAddress() function in inspector_socket.cc processes invalid octal format IP addresses during an --inspect session. This could allow attackers to execute arbitrary code.
