Weakness: CWE-78

Description

n8n before 2.29.8 and 2.30.x before 2.30.1 does not enforce shell sandbox restrictions on Linux and Windows in the @n8n/computer-use package (sandboxing was applied only on macOS). Shell commands executed by the tool run without any filesystem or network restrictions, allowing unrestricted access to the host filesystem and network from within the computer-use agent process. This issue only affects deployments where the @n8n/computer-use package is explicitly installed and running; standard n8n installations are not affected.

Affected products

n8n-io n8n: before 2.29.8; 2.30.0 (and their updates) — fixed in 2.29.8
n8n-io n8n: from 2.30.0 before 2.30.1 — fixed in 2.30.1

How to fix

Upgrade to a fixed version: n8n-io n8n 2.29.8; n8n-io n8n 2.30.1. Check the vendor advisory for mitigations.
