## Overview

n8n before 2.31.5 and before 2.32.1 contain a sandbox escape vulnerability in expression evaluation. An authenticated user with permission to create or modify workflows can craft expressions using arrow-function bodies to bypass the expression sandbox, triggering system command execution on the host running n8n. The issue is fixed in versions 2.31.5 and 2.32.1.

## Affected

- `n8n >= 2.32.0 < 2.32.1`
- `n8n < 2.31.5`

## Remediation
