Command Injection in n8n Computer-Use Package

Publication date: 2026-07-22

Last updated on: 2026-07-22

Assigner: VulnCheck

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.

Executive Summary

CVE-2026-65590 is a vulnerability in n8n versions before 2.30.1 and 2.29.8 where the @n8n/computer-use package fails to enforce shell sandbox restrictions on Linux and Windows. This allows shell commands executed by the tool to bypass filesystem and network restrictions, granting unrestricted access to the host system and network.

Detection Guidance

Check if the @n8n/computer-use package is installed and running on Linux or Windows systems. Review n8n version to confirm if it is below 2.29.8 or 2.30.1. Inspect logs for unauthorized shell command executions or unusual filesystem/network access patterns.

Impact Analysis

If exploited, this vulnerability could allow attackers with access to the computer-use agent to execute arbitrary commands on the host system, potentially leading to data breaches, system compromise, or further network infiltration. Exploitation requires the @n8n/computer-use package to be installed and running.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements such as GDPR (data protection) and HIPAA (health information privacy). Unrestricted filesystem and network access may result in data leaks or unauthorized modifications, posing significant compliance risks.

Mitigation Strategies

Upgrade n8n to version 2.29.8 or 2.30.1 or later to enforce sandbox restrictions. If the @n8n/computer-use package is not required, uninstall or disable it. Restrict access to the n8n instance and computer-use agent to trusted users only. Avoid using the --dangerously-disable-shell-sandbox flag unless absolutely necessary.
