SCA: security update for n8n (GHSA-x2mw-7j39-93xq)

critical Tenable Cloud Security Plugin ID 438092

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 2.2.0 and 1.123.8, an authenticated
 user with permission to create or modify workflows could chain the Read/Write Files from Disk node with
 git operations to achieve remote code execution. By writing to specific configuration files and then
 triggering a git operation, the attacker could execute arbitrary shell commands on the n8n host. The issue
 has been fixed in n8n versions 2.2.0 and 1.123.8. Users should upgrade to one of these versions or later
 to remediate the vulnerability. 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 Read/Write Files from Disk node by adding `n8n-nodes-base.readWriteFile` 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-2026-27498)
