SCA: security update for n8n (GHSA-fxcw-h3qj-8m8p)

high Tenable Self-Hosted Container Security Plugin ID 439230

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 2.6.4 and 1.123.23, an authenticated
user without permission to list external secrets could reference a secret by the external name in a
credential and retrieve its plaintext value when saving the credential. This bypassed the
`externalSecret:list` permission check and allowed access to secrets stored in connected vaults without
admin or owner privileges. This issue requires the instance to have an external secrets vault configured.
The attacker must know or be able to guess the name of a target secret. The issue has been fixed in n8n
versions 1.123.23 and 2.6.4. 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: Restrict n8n access to fully trusted users only, and/or disable external secrets
integration until the patch can be applied. These workarounds do not fully remediate the risk and should
only be used as short-term mitigation measures. (CVE-2026-33722)

Solution

Update the n8n library and its related packages to version 1.123.23 or later.
