When a\ndeferred operator passed a secret (for example a provider API key) into its\ntrigger, any authenticated user with DAG-scoped task-instance read access for\nthat DAG could read that secret in clear text while the task was deferred.\nUsers should upgrade to apache-airflow 3.3.0 or later, which masks sensitive\nvalues in trigger kwargs returned by the API.",
