Summary
n8n: Missing Token Validation on Microsoft Agent 365 Trigger and Stripe Nodes
Details

Impact

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.

Patches

The issue has been fixed in n8n versions 2.25.7, and 2.26.2. Users should upgrade to one of these versions or later to remediate the vulnerability.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

  • Deactivate any workflows using the Microsoft Agent 365 Trigger node or Stripe Trigger node until the instance can be upgraded.
  • Restrict network access to the n8n webhook endpoint to trusted sources only.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
