OS Command Injection in @n8n/computer-use (CVE-2026-65590)

Summary

OS command injection in @n8n/computer-use (CVE-2026-65590). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 2.29.8 or later.

Original description

The description as published by the source.

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.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r '@n8n/computer-use' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify
    grep -r '@n8n/computer-use' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で @n8n/computer-use を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch
    Upgrade @n8n/computer-use to 2.29.8

    ステージング環境で 2.29.8 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
