## Overview

A flaw in Node.js’s Permissions model allows attackers to bypass `--allow-fs-read` and `--allow-fs-write` restrictions using crafted relative symlink paths. By chaining directories and symlinks, a script granted access only to the current directory can escape the allowed path and read sensitive files. This breaks the expected isolation guarantees and enables arbitrary file read/write, leading to potential system compromise.
This vulnerability affects users of the permission model on Node.js v20,  v22,  v24, and v25.

## Affected

- `node.js >= 20.0.0, < 20.20.0`
- `node.js >= 22.0.0, < 22.22.0`
- `node.js >= 24.0.0, < 24.13.0`
- `node.js >= 25.0.0, < 25.3.0`

## Remediation

Upgrade past the affected range:

- `node.js 25.3.0`
