high Tenable Cloud Security Plugin ID 445199

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 2.27.4 and from 2.28.0 prior to 2.28.1, n8n
instances configured with more than one trusted token-exchange issuer resolved external identities to
local accounts using only the JWT sub claim and ignored the iss claim, allowing an attacker with a valid
token from one trusted issuer and a sub matching a victim under another issuer to authenticate as that
victim. This issue is fixed in versions 2.27.4 and 2.28.1. (CVE-2026-59208)

Solution

Update the n8n library and its related packages to version 2.27.4 or later.
