`fs.mkdtemp()` and `fs.mkdtempSync()` can be used to bypass the permission model check using a path traversal attack. This flaw arises from a missing check in the fs.mkdtemp() API and the impact is a malicious actor could create an arbitrary directory. This vulnerability affects all users using the experimental permission model in Node.js 20. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
