Background
Apache Airflow is an open-source platform used for programmatically authoring, scheduling, and monitoring workflows. It allows users to define complex workflows as Directed Acyclic Graphs (DAGs) and execute them on a distributed infrastructure. This vulnerability affects versions of Apache Airflow prior to 2.7.2. The vulnerability allows an authorized user with access to read specific DAGs to obtain information about task instances in other DAGs, potentially leading to unauthorized access to sensitive data.
Vulnerability Detail
The vulnerability in Apache Airflow arises from a flaw that allows an authorized user to read information about task instances in DAGs they do not have access to. This can occur when an authorized user has read access to specific DAGs and leverages this access to retrieve information about task instances in other DAGs. By exploiting this vulnerability, an attacker could gain unauthorized access to sensitive data or perform unauthorized actions within the affected system. It is important to note that this vulnerability only affects Apache Airflow versions prior to 2.7.2.
