Apache Airflow exposes deferred trigger kwargs in task-instance API responses

In Apache Airflow before 3.3.0, the REST API task-instance detail and list endpoints returned a deferred task's trigger kwargs without masking. When a deferred operator passed a secret for example a provider API key into its trigger, any authenticated user with DAG-scoped task-instance read acces...

Apache Airflow exposes unreadable DAG identifiers in the scheduling dependencies graph

A bug in Apache Airflow's /ui/dependencies scheduling graph endpoint applied the caller's readable-Dag filter to the top-level serialized Dag key but still emitted referenced Dag IDs through the dep.source and dep.target fields of trigger / sensor dependency entries. An authenticated UI user with...

Apache Airflow exposes sensitive JSON Variable values through the Bulk Variables API
