Path Validation Vulnerability (Updated 29-September-2017 - CVE assigned)
The Node.js project released a new version of 8.x this week which incorporates a security fix.
Version 8.5.0 of Node.js is vulnerable. 4.x and 6.x versions are NOT vulnerable.
Node.js-specific security flaws
Node.js version 8.5.0 included a change which caused a security vulnerability in the checks on paths made by some community modules. As a result, an attacker may be able to access file system paths other than those intended.
This problem was resolved within Node.js by partially reverting https://github.com/nodejs/node/commit/b98e8d995efb426bbdee56ce503017bdcbbc6332.
A CVE has been assigned as CVE-2017-14849
