SCA: security update for n8n (GHSA-756q-gq9h-fp22)

medium Tenable Cloud Security Plugin ID 440992

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 1.123.32, 2.17.4, and 2.18.1, an
 authenticated user with a valid API key scoped to variable:list could read variables from projects they
 are not a member of by supplying an arbitrary projectId query parameter to the public API variables
 endpoint. The handler queried the variables repository directly without enforcing project membership
 checks, bypassing the authorization-aware service layer used by the internal enterprise controller. If
 variables were misused to store sensitive information such as credentials or tokens, they should be
 rotated immediately. This issue only affects licensed enterprise or team deployments with multiple
 projects and the variables feature enabled. This issue has been patched in versions 1.123.32, 2.17.4, and
 2.18.1. (CVE-2026-42227)

Solution

Update the n8n library and its related packages to version 1.123.32 or later.
