Overview

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

Affected versions of this package are vulnerable to Privilege Escalation under certain conditions on Windows platforms. More specifically, improper configuration of permissions in the installation directory allows an attacker to perform two different escalation attacks: PATH variable hijacking and DLL hijacking.

Remediation

Upgrade node to version 16.4.1, 14.17.2, 12.22.2 or higher.
