How severe is CVE-2026-65590?

No CVSS score has been assigned to CVE-2026-65590 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-65590?

CVE-2026-65590 affects the following packages: n8n (npm), n8n (npm). Ecosystems affected: npm.

How do I fix CVE-2026-65590?

Update n8n to 2.30.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-65590 is resolved across your whole dependency graph.

How do I detect CVE-2026-65590 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for n8n, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-65590 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2026-65590 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-65590 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-65590?

CVE-2026-65590 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 47th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-65590?

CVE-2026-65590 is classified as OS Command Injection (CWE-78). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2026-65590 published, and has it been updated?

CVE-2026-65590 was published on July 22, 2026 and was last updated on October 21, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

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.
