CVE-2026-21894 is an authentication bypass vulnerability in the n8n workflow automation platform affecting versions 0.150.0 to before 2.2.2. The flaw exists in the Stripe Trigger node, where incoming webhook requests are not verified against the stored Stripe webhook signing secret. This allows unauthenticated attackers who know the webhook URL to send forged Stripe webhook events, triggering workflows without legitimate Stripe events. The risk is somewhat mitigated by the high-entropy UUID in the webhook URL, but authenticated users can view this URL, increasing exposure. Exploitation could lead to fake payment or subscription events influencing downstream processes. The vulnerability has been patched in version 2.
