SCA: security update for n8n (GHSA-33q9-f52j-gc75)

medium Tenable Cloud Security Plugin ID 445190

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- n8n before 2.28.0 (and before 2.27.4 on the 2.27.x branch) registers the DELETE /${restEndpoint}/test-
webhook/:id endpoint before authentication middleware is applied, allowing any unauthenticated network
caller who knows a workflow ID to cancel that workflow's active test webhook registration. The impact is
limited to disrupting in-progress test sessions; production webhooks, persistent workflow state, and
stored data are not affected. (CVE-2026-65014)

Solution

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