WID-SEC-2026-1168 · first 20.04.2026 · updated 20.04.2026 · CVSS 8,8
What it is about
Apache Airflow ist eine Plattform zur programmatischen Erstellung, Planung und Überwachung von Workflows. Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Apache Airflow und dem Airflow Keycloak Provider ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren und vertrauliche Informationen offenzulegen.
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 Programmcode auszuführen
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren
- vertrauliche Informationen offenzulegen
Am I affected?
Affected according to the BSI:
- Apache Airflow <3.2.0
- Apache Airflow Keycloak Provider <0.7.0
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Apache Airflow 3.2.0
- Apache Airflow Keycloak Provider 0.7.0
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.
