SCA: security update for n8n (GHSA-r4v6-9fqc-w5jr)

high Tenable Cloud Security Plugin ID 440990

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 1.123.33 and 2.17.5, the dynamic-
node-parameters endpoints did not verify whether the authenticated caller was authorized to use a supplied
credential reference. An authenticated user with access to a shared workflow could supply a foreign
credential ID in the request body, causing the backend to decrypt and use that credential in a helper
execution path where the caller also controls the destination URL. This allowed the caller to force the
backend to authenticate against attacker-controlled infrastructure using a credential belonging to another
user, effectively exfiltrating a reusable API key. The issue is not limited to any single node type; any
node that resolves credentials dynamically through these endpoints may be affected. This issue has been
patched in versions 1.123.33, 2.17.5, and 2.18.0. (CVE-2026-42226)

Solution

Update the n8n library and its related packages to version 1.123.33 or later.
