GHSA-5247-M8W9-2V4M
Vulnerability from github – Published: 2026-08-12 18:31 – Updated: 2026-08-12 18:31Apache 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.
