CVE-2026-49487

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 access for

that DAG could read that secret in clear text while the task was deferred.

Users should upgrade to apache-airflow 3.3.0 or later, which masks sensitive

values in trigger kwargs returned by the API.
