Secret disclosure via unredacted trigger kwargs
Published Jul 7, 2026 · Updated Jul 7, 2026
Information disclosure in Apache Airflow before 3.3.0 allows remote authenticated users to read deferred-task trigger secrets via its REST API. The TriggerResponse serializer converts decrypted trigger kwargs to a string and returns them in task-instance detail and list responses without redaction. DAG-scoped task-instance read access and a deferred operator that passes a secret to its trigger are required; exposed values can include API keys or tokens.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
