SCA: security update for n8n (GHSA-5m98-cgcr-xx3q)

medium Tenable Self-Hosted Container Security Plugin ID 447912

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 1.123.76, 2.37.7, and 2.38.2, the GitHub
 Trigger generated a webhook secret but discarded it when GitHub returned HTTP 422 and the node reused an
 existing webhook. Workflow static data then retained webhookId without webhookSecret, and X-Hub-
 Signature-256 verification accepted deliveries without a stored secret. The affected logic includes
 packages/nodes-base/nodes/Github/GithubTriggerHelpers.ts and the 422 webhook reuse path. This issue is
 fixed in versions 1.123.76, 2.37.7 and 2.38.2. (CVE-2026-86080)

Solution

Update the n8n library and its related packages to version 1.123.76 or later.
