n8n: Mehrere Schwachstellen
WID-SEC-2026-3165 · first 03.09.2026 · updated 17.09.2026 · CVSS 9,9
What it is about
n8n ist ein Workflow-Automatisierungstool, mit dem verschiedene Anwendungen und Dienste miteinander verbunden werden können, um Aufgaben zu automatisieren. Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in n8n ausnutzen, um Sicherheitsmechanismen zu umgehen, beliebigen Code auszuführen oder einen Denial of Service zu verursachen.
Under what conditions?
Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.
What can happen in the worst case
An attacker could use the vulnerability to
- Sicherheitsmechanismen zu umgehen
- beliebigen Code auszuführen oder einen Denial of Service zu verursachen
Am I affected?
Affected according to the BSI:
- n8n n8n <1.123.76
- n8n n8n <2.38.2
- n8n n8n <2.37.7
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- n8n n8n 1.123.76
- n8n n8n 2.38.2
- n8n n8n 2.37.7
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
