CVE-2026-65016 n8n before 1.123.64, 2.29.8, and 2.30.1 Privilege Escalation via SSO Instance-Role

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-exchang...
