CVE-2026-58076
NVD: Apache Airflow's serialization layer reconstructed exception nodes by calling import_string() on a class name taken from the serialized blob and instantiating it with arguments from the same blob, with no restriction on what could be imported. NVD: An operator's executor_config reaches that branch, so a Dag author could place a value there that causes an arbitrary callable to be imported and invoked -- for example subprocess.check_output, or builtins.eval on the builtins-prefixed variant. NVD: The code runs in the **Scheduler**, which reconstructs serialized Dags in its normal loop with no request involved, and in the **API server**, on any authenticated read of the Dag such as GET /api/v2/dags/{dag_id}/details.
