# n8n Local Gateway: deep link silently re-pairs to attacker instance

n8n's Local Gateway desktop app accepts an n8n-computer-use:// deep link that re-pairs it with a different n8n instance without confirmation. An attacker who lures a user into opening a crafted link can act on the user's computer through the gateway with the permissions already granted.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Local Gateway version against the fixed releases listed in the advisory, and look for n8n Local Gateway in the desktop app list.
- Confirm which n8n instance the Local Gateway is paired with in its settings.

## Fix

- Upgrade n8n to `2.41.4` or later on the 2.41 line, or to `2.42.1` or later on the 2.42 line.
- Revoke and re-pair the Local Gateway after upgrading if an unknown instance was paired.

## Timeline

## From the sources

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.
