CVE-2026-58076

Apache Airflow CVE-2026-58076 describes an unguarded import_string() deserialization path in the serialization layer (BaseSerialization.deserialize) that can import and invoke arbitrary callables via a serialized blob placed in executor_config. The vulnerability can be triggered by a DAG author a...
