Apache Airflow exposes deferred trigger kwargs in task-instance API responses
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | apache-airflow | < 3.3.0 | 3.3.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
