This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
