Description

A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Affected products

Node.js: from 20.0.0 before 20.8.1 — fixed in 20.8.1

How to fix

Upgrade to a fixed version: Node.js 20.8.1. Check the vendor advisory for mitigations.
