Overview

CVE-2026-65016 is a high-severity vulnerability. It was published on July 22, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
