SCA: security update for n8n (GHSA-jjpj-p2wh-qf23)

critical Tenable Self-Hosted Container Security Plugin ID 438035

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 exploit a vulnerability in the
JavaScript Task Runner sandbox to execute arbitrary code outside the sandbox boundary. On instances using
internal Task Runners (default runner mode), this could result in full compromise of the n8n host. On
instances using external Task Runners, the attacker might gain access to or impact other task executed on
the Task Runner. Task Runners must be enabled using `N8N_RUNNERS_ENABLED=true`. The issue has 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 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 use external runner mode (`N8N_RUNNERS_MODE=external`) to limit the blast radius. These
workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
