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.
