Overview

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

Affected versions of this package are vulnerable to DNS rebinding. A malicious website could use a DNS rebinding attack to trick the web browser to bypass same-origin-policy checks and to allow HTTP connections to localhost or to hosts on the local network. If a Node.js process with the debug port active is running on localhost or on a host on the local network, the malicious website could connect to it as a debugger, and get full code execution access.

Remediation

Upgrade node to version 6.14.0, 8.11.0, 9.10.0 or higher.
