Apache Airflow: Task-instance API exposes secrets in deferred trigger kwargs
Published Jul 7, 2026

MEDIUMCVSS 3.1
EPSS 0.66%
Description
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.
