SCA: security update for n8n (GHSA-wxx7-mcgf-j869)

critical Tenable Cloud Security Plugin ID 438060

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-27497)
