Description

This security bulletin contains information about 1 security vulnerability.


1) Improper Access Control (CVE-ID: CVE-2026-21715)

The vulnerability allows a local user to disclose file existence and resolve symlinks.

The vulnerability exists due to improper access control in fs.realpathSync.native() within the Node.js Permission Model when accessing filesystem paths. A local user can run code under --permission with restricted --allow-fs-read to use fs.realpathSync.native() and determine file existence, resolve symlink targets, and enumerate paths outside permitted directories.

This bypass affects only environments using the Permission Model with intentionally restricted filesystem read permissions.


Remediation

Install update from vendor's website.
