Description

A vulnerability has been identified in Node.js, specifically affecting the handling of drive names in the Windows environment. Certain Node.js functions do not treat drive names as special on Windows. As a result, although Node.js assumes a relative path, it actually refers to the root directory. On Windows, a path that does not start with the file separator is treated as relative to the current directory. This vulnerability affects Windows users of `path.join` API.

Affected products

• Node.js: from 18.0 before 18.20.6; from 20.0 before 20.18.2; from 22.0 before 22.13.1; from 23.0 before 23.6.1 — fixed in 18.20.6, 20.18.2, 22.13.1, 23.6.1

How to fix

Upgrade to a fixed version: Node.js 18.20.6, 20.18.2, 22.13.1, 23.6.1. Check the vendor advisory for mitigations.
