MediumCVSS 5.6

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.

Before you act

Start with the vendor's bulletin.

We normalize the fields that vendors publish so you can search and compare advisories in one place. We do not replace the original bulletin or turn a product-name match into proof that a system is vulnerable.

Confirm the installed product and version, read the linked vendor guidance, and test the recommended update or mitigation through your normal change process.

How we check our sources
