      "value": "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."

      "value": "El endpoint de materialización de activos de Apache Airflow (“POST /api/v2/assets/{asset_id}/materialize”) y la verificación de resultados de XCom en “wait_dag_run_until_finished” autorizó el Dag objetivo sin su equipo, a diferencia de cualquier otro sitio de autorización. Un gestor de autorización consciente del equipo distingue un Dag con ámbito de equipo de uno global por ese campo -- el gestor de autorización de Keycloak, por ejemplo, verifica el recurso “DAG” en lugar de “DAG:[team]” -- por lo que el permiso con ámbito de equipo que debería restringir la solicitud nunca fue consultado. En una implementación ejecutyo el modo multi-equipo con un gestor de autorización consciente del equipo, un usuario autenticado en un equipo podría activar ejecuciones de Dag pertenecientes a otro equipo, suministryo su propio “dag_run_id” y “conf”, y podría leer los valores XCom de otro equipo. Las implementaciones que utilizan el gestor de autorización FAB no se ven afectadas, ya que no tiene soporte multi-equipo. Se aconseja a los usuarios actualizar a apache-airflow 3.3.1 o posterior, lo que resuelve el equipo del Dag en ambos sitios."
