SCA: security update for n8n (GHSA-cw9w-vv67-hf73)

medium Tenable Cloud Security Plugin ID 447920

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 2.37.7 and 2.38.1, the OAuth token endpoint
 bound an authorization code's first access token to the consented resource but did not bind its refresh
 token. Refreshing checked only that the requested resource was registered, not that it matched the
 original grant. An OAuth client approved for one workflow could substitute a different workflow URL in the
 resource parameter and obtain a valid token for an unapproved workflow accessible to the consenting user.
 This issue is fixed in versions 2.37.7 and 2.38.1. (CVE-2026-86073)

Solution

Update the n8n library and its related packages to version 2.37.7 or later.
