Background
Apache Airflow is an open-source platform used for programmatically authoring, scheduling, and monitoring workflows. It allows users to define tasks and their dependencies as Directed Acyclic Graphs (DAGs) and execute them on a distributed infrastructure. Apache Airflow is widely adopted for its flexibility and scalability in managing complex workflows.
Vulnerability Detail
Apache Airflow versions before 2.7.2 are vulnerable to sensitive information exposure. This vulnerability allows an authorized user with access to read specific DAGs to also read information about task instances in other DAGs. This means that an attacker with access to one DAG can potentially gain unauthorized access to sensitive information from other DAGs. The impact of this vulnerability depends on the sensitivity of the information stored in the affected DAGs.
