Vulnerability from cleanstart – Published: 2026-10-10 00:41 – Updated: 2026-10-09 07:45 – Source website

Summary

Details

Security vulnerability affects the airflow-3 package. Apache Airflow's asset materialization endpoint (POST /api/v2/assets/{asset_id}/materialize) and the XCom result check on wait_dag_run_until_finished authorized the target Dag without its team, unlike every other authorization site.

Severity

6.5 (Medium)

Title

Apache Airflow: Cross-team authorization bypass in the asset materialization and dag-run result endpoints

Summary

Apache Airflow's asset materialization endpoint (`POST /api/v2/assets/{asset_id}/materialize`) and the XCom result check on `wait_dag_run_until_finished` authorized the target Dag without its team, unlike every other authorization site. A team-aware auth manager distinguishes a team-scoped Dag from a global one by that field -- the Keycloak auth manager, for example, checks the `DAG` resource instead of `DAG:<team>` -- so the team-scoped permission that should gate the request was never consulted. In a deployment running multi-team mode with a team-aware auth manager, an authenticated user in one team could trigger Dag runs belonging to another team, supplying their own `dag_run_id` and `conf`, and could read another team's XCom values. Deployments using the FAB auth manager are unaffected, as it has no multi-team support. Users are advised to upgrade to apache-airflow 3.3.1 or later, which resolves the Dag's team at both sites.
