Which versions of AI / ML are affected by CVE-2026-27497?

Authenticated users with workflow modification permissions in n8n can execute arbitrary code and write files to the server, potentially compromising the entire automation platform and connected…. A patch is available.

How to fix or mitigate CVE-2026-27497?

Within 24 hours: Audit all n8n user accounts and restrict workflow modification permissions to essential personnel only; disable the Merge node SQL query mode if not actively required. Within 7 days: Implement network segmentation to isolate the n8n server and restrict outbound connections; monitor for suspicious SQL queries and file write operations. Within 30 days: Upgrade to patched versions (2.10.1, 2.9.3, or 1.123.22 depending on current deployment) as soon as available; conduct a full security audit of workflows for unauthorized code or file operations.

DescriptionGitHub Advisory

n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, an authenticated user with permission to create or modify workflows could leverage the Merge node's SQL query mode to execute arbitrary code and write arbitrary files on the n8n server. 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 disable the Merge node by adding n8n-nodes-base.merge to the NODES_EXCLUDE environment variable. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

AnalysisAI

Authenticated users with workflow modification permissions in n8n versions prior to 2.10.1, 2.9.3, and 1.123.22 can exploit the Merge node's SQL query mode to execute arbitrary code and write files on the server. This high-severity vulnerability (CVSS 8.8) affects the AI/ML and workflow automation platform, allowing attackers with legitimate access to achieve complete system compromise. No patch is currently available, and administrators should restrict workflow permissions or disable the Merge node as temporary mitigations.
