SCA: security update for n8n (GHSA-35q8-9mj6-wjmf)
high Tenable Self-Hosted Container Security Plugin ID 445154
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 privilege escalation vulnerability in
Enterprise SSO instance-role provisioning. The provisioning path maps an IdP-asserted role claim to an n8n
global role but does not prevent assignment of the global:owner role (unlike the token-exchange identity
path, which rejects it). An SSO-authenticated user whose instance-role claim resolves to global:owner is
provisioned as instance owner, gaining full administrative control over workflows, credentials, users, and
instance configuration. Exploitation requires that Enterprise SSO is configured, instance-role
provisioning is enabled via N8N_SSO_SCOPES_PROVISION_INSTANCE_ROLE (disabled by default), and the attacker
controls the instance-role claim value issued by the IdP. (CVE-2026-65016)
Solution
Update the n8n library and its related packages to version 1.123.64 or later.See Also
