GHSA-vjf3-2gpj-233v: n8n has an SSO Enforcement Bypass in its Self-Service Settings API

An authenticated user signed in through Single Sign-On (SSO) could disable SSO enforcement for their own account through the n8n API. This allowed the user to create a local password and authenticate directly with email and password, completely bypassing the organization’s SSO policy, centralized identity management, and any identity-provider-enforced multi-factor authentication.
