SCA: security update for n8n (GHSA-2j5h-858j-5mpf)

high Tenable Cloud Security Plugin ID 443313

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 1.123.55, 2.25.7, and 2.26.2, three EE
 endpoints used by the Dynamic Credentials feature accepted any authenticated n8n session without
 performing per-resource ownership or scope checks on the target workflow or credential. An authenticated
 user with no project membership or credential sharing relationship could enumerate credential identifiers,
 names, and types referenced by any private workflow in the instance, initiate an OAuth authorization flow
 against another user's credential to overwrite its stored tokens with tokens bound to an account they
 control, or revoke another user's stored credential tokens entirely. Workflows relying on a hijacked
 credential would subsequently execute under the attacker's OAuth identity, enabling data exfiltration to
 attacker-controlled external services and persistent takeover of integrations. Token revocation would
 break affected workflows. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2. (CVE-2026-54305)

Solution

Update the n8n library and its related packages to version 1.123.55 or later.
