CyberRota Analysis
AI-GeneratedThe vulnerability affects n8n versions prior to 1.123.64, 2.29.8, and 2.30.1, allowing an attacker with SSO authentication to escalate privileges to the global:owner role through a misconfigured Enterprise SSO instance-role provisioning. This exploitation grants full administrative control over workflows, credentials, users, and instance configurations. Organizations using n8n with Enterprise SSO enabled should prioritize patching to mitigate the risk of unauthorized access and potential data breaches.

Original NVD 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.
