Kubernetes (ingress-nginx): Mehrere Schwachstellen
WID-SEC-2026-0289 · first 03.02.2026 · updated 09.02.2026 · CVSS 8,8
What it is about
Kubernetes ist ein Werkzeug zur Automatisierung der Bereitstellung, Skalierung und Verwaltung von containerisierten Anwendungen. Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Kubernetes ausnutzen, um beliebigen Code auszuführen, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen und einen Denial-of-Service-Zustand 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
- beliebigen Code auszuführen
- Sicherheitsmaßnahmen zu umgehen
- vertrauliche Informationen offenzulegen
- einen Denial-of-Service-Zustand zu verursachen
Am I affected?
Affected according to the BSI:
- SUSE Linux
- Open Source Kubernetes Ingress NGINX <1.13.7
- Open Source Kubernetes Ingress NGINX <1.14.3
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Kubernetes Ingress NGINX 1.13.7
- Open Source Kubernetes Ingress NGINX 1.14.3
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.
