SCA: security update for n8n (GHSA-vpcf-gvg4-6qwr)

critical Tenable Cloud Security Plugin ID 438014

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,
 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.
 (CVE-2026-27577)
