Ein entfernter, authentisierter oder anonymer Angreifer kann mehrere Schwachstellen in n8n ausnutzen, um beliebigen Code auszuführen, sich erhöhte Berechtigungen zu verschaffen, Cross-Site-Scripting-Angriffe durchzuführen und vertrauliche Informationen offenzulegen. Über einige dieser Schwachstellen sind weitere Angriffe möglich, wie beispielsweise die Übernahme von Konten, das Hijacking von Sitzungen und die vollständige Kompromittierung des Systems.

## Impact Vulnerabilities in the Git node allowed authenticated users with permission to create or modify workflows to execute arbitrary system commands or read arbitrary files on the n8n host. ## Patches The issue has been fixed in n8n versions 2.5.0, and 1.123.10. Users should upgrade to this version or later to remediate the vulnerability. ## Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Limit workflow creation and editing permissions to fully trusted users only. - Restrict or disable access to the Git node if not essential for operations. - Deploy n8n in a hardened environment with restricted operating system privileges and network access to reduce the impact of potential exploitation. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures. ## Resources - [n8n Documentation — Blocking nodes](https://docs.n8n.io/hosting/securing/blocking-nodes/) — how to globally disable specific nodes --- n8n has adopted CVSS 4.0 as primary score for all security advisories. CVSS 3.1 vector strings are provided for backward compatibility. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
