NewCVE-2026-33660 (opens in a new tab)How to fix?
Upgrade n8n to version 1.123.27, 2.13.3, 2.14.1 or higher.
Overview
n8n is a n8n Workflow Automation Tool
Affected versions of this package are vulnerable to Arbitrary Code Injection via the Merge node's Combine by SQL mode. An authenticated user with permissions to create or modify workflows can execute arbitrary code and access sensitive files on the host by crafting malicious SQL statements when creating or modifying workflows.
Workaround
This vulnerability can be mitigated by limiting workflow creation and editing permissions to fully trusted users only, or by disabling the Merge node by adding n8n-nodes-base.merge to the NODES_EXCLUDE environment variable.
