SCA: security update for n8n (GHSA-2p9h-rqjw-gm92)

high Tenable Cloud Security Plugin ID 438084

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 inject arbitrary scripts into pages
rendered by the n8n application using different techniques on various nodes (Form Trigger node, Chat
Trigger node, Send & Wait node, Webhook Node, and Chat Node). Scripts injected by a malicious workflow
execute in the browser of any user who visits the affected page, enabling session hijacking and account
takeover. The issues have been fixed in n8n versions 2.10.1 and 1.123.21. 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 Webhook node by adding `n8n-nodes-
base.webhook` 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-2026-27578)
