NVD description
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.
What to do
- Upgrade n8n to
2.25.7or later (or the patched release of your branch: 2.26.2). - Do not expose the component's API or UI to the internet without authentication in front of it.
