This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Node.js Permission Model does not clarify in the documentation that wildcards should be only used as the last character of a file path. For example:

```

--allow-fs-read=/home/node/.ssh/*.pub

```

will ignore `pub` and give access to everything after `.ssh/`.

This misleading documentation affects all users using the experimental permission model in Node.js 20 and Node.js 21.

Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
