CVE-2023-32003

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. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js. This vulnerability affects all users using the experimental permission model in Node.js 20.

From what I gather the experimental permission model was introduced in version 20, so only openSUSE:Factory/nodejs20 would affected.

It's been introduced some time ago, so initial parts of it were backported all the way to v12. But most of the bugs are only in the newer versions.
