Background
Apache Airflow is an open-source platform designed to programmatically author, schedule, and monitor workflows. It allows users to define workflows as Directed Acyclic Graphs (DAGs) and is widely used in data engineering and data science projects. The platform supports multi-team environments, enabling different teams to manage their own DAGs while maintaining security and access controls. However, a recent vulnerability has been identified that affects the authorization checks for team-scoped DAGs, potentially allowing unauthorized access to sensitive data.
Vulnerability Detail
The vulnerability arises from the asset materialization endpoint and the XCom result check on the 'wait_dag_run_until_finished' function, which improperly authorizes DAG runs without considering the team context. This flaw allows an authenticated user from one team to trigger DAG runs belonging to another team, potentially exposing sensitive XCom values. The issue is particularly critical in deployments using a team-aware authorization manager, such as Keycloak, which fails to enforce team-specific permissions. As a result, this could lead to unauthorized data access and manipulation, impacting the integrity and confidentiality of the workflows.
How To Fix
Latest published version: 3.3.2 as of 22 Oct 2026
