Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · unedited
n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, additional exploits in the expression evaluation of n8n have been identified and patched following CVE-2025-68613. An authenticated user with permission to create or modify workflows could abuse crafted expressions in workflow parameters to trigger unintended system command execution on the host running n8n. The issues have been fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22. Users should upgrade to one of these versions or later to remediate all known vulnerabilities. If upgrading is not immediately possible, administrators should consider the following temporary mitigations. Limit workflow creation and editing permissions to fully trusted users only, and/or deploy n8n in a hardened environment with restricted operating system privileges and network access to reduce the impact of potential exploitation. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

dbcve analysis · high confidence
Command injection vulnerability in n8n's expression evaluation feature allows authenticated users with workflow creation/modification permissions to execute arbitrary system commands via crafted expressions. This is a follow-up patch to CVE-2025-68613, affecting versions prior to 2.10.1, 2.9.3, and 1.123.22.
MitigationUpgrade to n8n versions 2.10.1, 2.9.3, or 1.123.22 or later. If immediate upgrade is not possible, limit workflow permissions to trusted users and deploy in a hardened environment as temporary mitigation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checks
Work through these to decide whether this CVE applies to you.
Identify installed n8n version
Run `n8n --version` or check the version displayed in the n8n UI (typically in the footer or admin area). If running via Docker, check the image tag. If self-hosted, check package.json or the version endpoint if available.
Affected if The installed version falls into any of these ranges: < 1.123.22, >= 2.0.0 to < 2.9.3, or >= 2.10.0 to < 2.10.1
Confirm workflow permissions exist
Review user roles and permissions in n8n. Check if any user accounts (other than fully trusted administrators) have the ability to create or edit workflows. This can be done via the n8n UI under Settings > Users or by reviewing your authentication/authorization configuration.
Affected if Any user account with workflow creation or modification permissions exists in the system (this is the prerequisite for the vulnerability to be exploitable)
Verify expression evaluation feature is accessible
Confirm that non-admin users with workflow permissions can access the expression editor within the workflow builder. This is typically available in the expression editor panel when editing a node in a workflow.
Affected if The expression editor is accessible to users who have workflow create/edit permissions (this is the attack surface for the command injection)
You are affected if your n8n installation version is less than 1.123.22, or between 2.0.0 and 2.9.3, or between 2.10.0 and 2.10.1, AND any user with workflow creation/modification permissions can access the expression editor.

Upgrade availableUpgrade to 1.123.22 / 2.9.3 / 2.10.1 or later
Upgrade to n8n versions 2.10.1, 2.9.3, or 1.123.22 or later. If immediate upgrade is not possible, limit workflow permissions to trusted users and deploy in a hardened environment as temporary mitigation.
Recommended fixHigh confidence
Upgrade to n8n version 1.123.22, 2.9.3, or 2.10.1 (or later) depending on your current branch
1. Back up your existing n8n installation and database before proceeding with the upgrade
2. Upgrade n8n to one of the fixed versions: version 1.123.22 or later (for 1.x branch), version 2.9.3 or later (for 2.0.x-2.9.x branch), or version 2.10.1 or later (for 2.10.x branch)
3. Verify the upgrade was successful by checking the n8n version in the UI or CLI
4. Test that existing workflows function correctly after the upgrade
5. If upgrading is not immediately possible, temporarily restrict workflow creation and editing permissions to fully trusted users only as an interim mitigation
Caveat No breaking changes mentioned in the advisory; upgrade to the appropriate version for your current branch

This CVE is a follow-up to CVE-2025-68613, meaning the initial fix was incomplete. That's a signal you need to weigh carefully: the advisory now tells you to restrict workflow creation permissions to fully trusted users. Read that as what it is — not a temporary measure, but the actual mitigation. The n8n team has concluded that expression evaluation cannot be secured for untrusted or semi-trusted users, and they've moved the security boundary upstream to the workflow creator. That's the fix. The code will keep getting patched; the permission guidance is what's staying.
The CVSS 9.9 with authentication required tells you something important about blast radius. This isn't a narrow admin-only path — it's accessible to any authenticated user who can create or edit workflows. In most n8n deployments, that group is intentionally broad because the platform's value proposition is enabling non-technical users to build automations. That same flexibility is now your attack surface. You cannot segment this blast radius without dismantling what n8n is designed to do.
Your immediate actions: audit who can create or edit workflows in your deployment. If that list includes anyone beyond a defined set of administrators, you're exposed. Check whether the expression evaluation feature is actually necessary for your workflows — disabling it reduces attack surface while you plan upgrades. The version fixes are 1.123.23 for the legacy branch and 2.10.2 or 2.9.4 for the 2.x series, but patching alone doesn't solve the underlying trust model. Even after upgrading, anyone who can author workflows still has a evaluation path into the system.
The deeper problem is operational, not technical: you likely have production workflows built over years by users who were explicitly trusted to create automations. Those workflows now operate in a security context the platform itself has walked back. Re-audit or re-architect automations built under assumptions that no longer hold. This isn't a patch-and-move-on vulnerability — it's a re-evaluation of who you trust with workflow creation, and that question doesn't have a software update answer.
