## Overview

n8n before 2.41.4 and 2.42.x before 2.42.1 contains a missing confirmation vulnerability in the Local Gateway desktop app that allows its deep-link connect handler to silently re-pair the app with a different n8n instance. Attackers can lure users running the Local Gateway into opening a crafted n8n-computer-use:// link to connect their computer to an attacker-controlled instance, inheriting previously granted permissions and acting on the computer through the gateway.

## Affected

- `n8n >= 2.42.0 < 2.42.1`
- `n8n < 2.41.4`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
