CVE-2026-49298Network attack vector

Authenticated Execution API takeover via exposed JWT arguments

Published Jun 1, 2026 · Updated Jun 1, 2026

JWT exposure in Apache Airflow before 3.2.2 allows remote authenticated users to assume worker-task privileges through Kubernetes pod data. KubernetesExecutor inserts an Execution API JWT into each worker container's command-line arguments, making it readable from the pod specification. Exploitation requires UI or API authentication, Kubernetes pods/get access in the Airflow namespace, and a KubernetesExecutor deployment; the stolen token permits state-changing Execution API calls and access to Variables, Connections, and XComs.
