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. 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.
