EPSS · scored 2026-10-23

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.

    Ein Angreifer kann mehrere Schwachstellen in n8n ausnutzen, um beliebigen Code auszuführen, Sicherheitsmaßnahmen zu umgehen, SQL-Injection- und Cross-Site-Scripting-Angriffe durchzuführen, Daten zu manipulieren, einen Denial-of-Service-Zustand zu verursachen oder vertrauliche Informationen offenzulegen, was weitere Angriffe einschließlich einer Rechteausweitung ermöglichen kann.

    ## 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.
