## Description

`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.
