Overview
n8n is a n8n Workflow Automation Tool
Affected versions of this package are vulnerable to Improper Authentication via the Self-Service Settings API. An attacker can circumvent centralized identity management and multi-factor authentication by disabling SSO enforcement for their own account and creating local credentials after authenticating through SSO.
