What it is about

Apache Airflow ist eine Plattform zur programmatischen Erstellung, Planung und Überwachung von Workflows. Ein Angreifer kann mehrere Schwachstellen in Apache Airflow ausnutzen, um seine Privilegien zu erhöhen, beliebigen Code auszuführen, Sicherheitsmaßnahmen zu umgehen oder Daten zu manipulieren und offenzulegen.

Under what conditions?

The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.

What can happen in the worst case

An attacker could use the vulnerability to

  • seine Privilegien zu erhöhen
  • beliebigen Code auszuführen
  • Sicherheitsmaßnahmen zu umgehen oder Daten zu manipulieren
  • offenzulegen

  • Apache Airflow FAB Provider <3.9.0
  • Apache Airflow Keycloak Provider <0.10.0
  • Apache Airflow Kafka Provider <2.0.0
  • Apache Airflow Akeyless Provider <0.3.1

The installed version is usually shown under “Help → About” or in the device’s admin interface.

  • Apache Airflow Keycloak Provider 0.10.0
  • Apache Airflow Kafka Provider 2.0.0
