SCA: security update for n8n (GHSA-9r8p-h6cc-6qhm)

medium Tenable Self-Hosted Container Security Plugin ID 445123

Description

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

- n8n versions before 1.123.64, 2.29.8, and 2.30.1 contain a credential exposure vulnerability: when
configured with a Google Service Account key, the full PEM private key was mistakenly placed in the JWT
header's kid field (intended only for a key identifier). Because JWT headers are Base64-encoded rather
than encrypted, the private key could be recovered by anything that logged or inspected the JWT. An
attacker who obtained the key could impersonate the service account and access or modify any Google Cloud
resource it was authorized to use. Only instances using Google Service Account credentials are affected.
(CVE-2026-65599)

Solution

Update the n8n library and its related packages to version 1.123.64 or later.
