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."}, {"lang": "es", "value": "El endpoint de materializaci\u00f3n de activos de Apache Airflow (\u201cPOST /api/v2/assets/{asset_id}/materialize\u201d) y la verificaci\u00f3n de resultados de XCom en \u201cwait_dag_run_until_finished\u201d autoriz\u00f3 el Dag objetivo sin su equipo, a diferencia de cualquier otro sitio de autorizaci\u00f3n. Un gestor de autorizaci\u00f3n consciente del equipo distingue un Dag con \u00e1mbito de equipo de uno global por ese campo -- el gestor de autorizaci\u00f3n de Keycloak, por ejemplo, verifica el recurso \u201cDAG\u201d en lugar de \u201cDAG:[team]\u201d -- por lo que el permiso con \u00e1mbito de equipo que deber\u00eda restringir la solicitud nunca fue consultado.
