CVE-2026-118677: n8n Local Gateway deep-link missing confirmation re-pairing

CVE-2026-118677 · Severity: medium · CVSS 5.9 · Published 2026-10-28

n8n's Local Gateway desktop app is a tool that allows remote automation workflows to access and control a user's computer. An attacker can trick a user into opening a malicious link that silently re-pairs the app to an attacker-controlled n8n instance, automatically inheriting the permissions previously granted to the app. This enables the attacker to remotely execute actions on the user's computer through the compromised gateway.

How to fix

Fixed in: 2.42.1, 2.41.4

Do not open unsolicited links using the n8n-computer-use:// scheme. Quit the Local Gateway app when not actively in use. Restrict the allowedOrigins setting to the specific instance URL rather than using the default wildcard. Disable the Computer Use / Local Gateway feature if it is not required.

Technical details

The Local Gateway's deep-link handler (n8n-computer-use:// scheme) fails to require user confirmation before re-pairing to a different n8n instance. The vulnerability is triggered when an attacker-controlled URI is opened by a user, causing the app to silently reconnect and preserve all previously granted permissions. Attack requires the Local Gateway app to be installed and running, user interaction to open a crafted link, and a network connection; a fix is available in versions 2.42.1 and 2.41.4.

Affected products
