Description
In Apache Airflow before 3.3.0, the REST API task-instance detail and list<br />
endpoints returned a deferred task&#39;s trigger kwargs without masking. When a<br />
deferred operator passed a secret (for example a provider API key) into its<br />
trigger, any authenticated user with DAG-scoped task-instance read access for<br />
that DAG could read that secret in clear text while the task was deferred.<br />
Users should upgrade to apache-airflow 3.3.0 or later, which masks sensitive<br />
values in trigger kwargs returned by the API.
