Vulnerability from github – Published: 2026-07-22 22:28 – Updated: 2026-07-22 22:28

Summary

n8n: computer-use Shell Sandbox Not Enforced on Linux and Windows

Details

Impact

The shell tool in the @n8n/computer-use package applied its sandbox restrictions only on macOS. On Linux and Windows, shell commands executed by the tool ran 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. It does not affect standard n8n installations.

Patches

The issue has been fixed in n8n versions 2.29.8 and 2.30.1. Users should upgrade to one of these versions or later to remediate the vulnerability.

The fix adds sandbox enforcement on Linux via bubblewrap and disables the shell tool entirely when a working sandbox cannot be established. An explicit opt-out flag (--dangerously-disable-shell-sandbox) is available for deployments that require unsandboxed shell access and accept the associated risk.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Disable or avoid deploying the @n8n/computer-use package on Linux or Windows hosts until the fix is applied. - Restrict access to the n8n instance and the computer-use agent to fully trusted users only.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

CVE-2026-65590 (GCVE-0-2026-65590)

Vulnerability from cvelistv5 – Published: 2026-07-22 11:21 – Updated: 2026-07-22 13:03

Title

n8n before 2.30.1 Shell Sandbox Bypass on Linux Windows

Summary

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.
