CVE-2026-31987Network attack vector

DAG-author impersonation via logged task JWTs

Published Apr 16, 2026 · Updated Apr 16, 2026

Sensitive-data exposure in Apache Airflow 3.0.0 through versions before 3.2.0 allows remote authenticated users to read task JWTs in logs. BaseWorkloadSchema leaves its token field in Pydantic's generated representation, and execute_workload logs the workload object with the raw JWT. Any UI user who can read an affected task log can reuse the JWT for API access and perform actions granted to a DAG author.
