# CVE-2026-54308

> 6.3 MEDIUM · 🧪 PoC

## Beschreibung

n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, the MicrosoftAgent365Trigger and StripeTrigger node did not validate that inbound requests. As a result, an unauthenticated attacker who knows the webhook URL could submit a forged payload and cause the workflow to execute with attacker-controlled data. This vulnerability is fixed in 2.25.7 and 2.26.2.
