Security Impact
CVSS: 8.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix GHSA-365g-vjw2-grx8
To remediate this vulnerability, upgrade all affected n8n dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install n8n-nodes-base@Latest secure releasenpm install n8n@Latest secure releaseRun the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls n8n-nodes-baseHow to Check if You Are Affected
To determine whether your Node.js application is affected by GHSA-365g-vjw2-grx8, inspect your project dependencies using npm:
npm ls n8n-nodes-baseAnalyze the terminal output to locate any version of n8n in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The npm ls n8n-nodes-base command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In n8n, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n\nThe `Execute Command` node in n8n allows execution of arbitrary commands on the host system where n8n runs. While this functionality is intended for advanced automation and can be useful in certain workflows, it poses a security risk if all users with access to the n8n instance are not fully trusted.\n\nAn attacker—either a malicious user or someone who has compromised a legitimate user account—could exploit this node to run arbitrary commands on the host machine, potentially leading to data exfiltration, service disruption, or full system compromise.\n\nThis vulnerability affects all n8n deployments where:\n\n- The `Execute Command` node is enabled, and\n- Not all user accounts are strictly controlled and trusted.\n\nn8n.cloud is **not** impacted.\n\n\n### Patches\nNo code changes have been made to alter the behavior of the `Execute Command` node. The recommended mitigation is to disable the node by default in environments where it is not explicitly required.\n\nFuture n8n versions may change the default availability of this node.\n\n### Workarounds\nAdministrators can disable the `Execute Command` node by setting the following environment variable before starting n8n:\n\n```bash\nexport NODES_EXCLUDE: \"[\\\"n8n-nodes-base.executeCommand\\\"]\"\n```\n\n### References\nn8n docs: [Execute Command](https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-base.executecommand/)\nn8n docs: [Blocking nodes](https://docs.n8n.io/hosting/securing/blocking-nodes/)",
