## Description

A vulnerability has been identified in Node.js version 20, affecting users
of the experimental permission model when the --allow-fs-read flag is used
with a non-\* argument.
This flaw arises from an inadequate permission model that fails to restrict
file stats through the `fs.statfs` API. As a result, malicious actors can
retrieve stats from files that they do not have explicit read access to.
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.
