No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

JWT tokens that were used by workers in Kubernetes Executors have been exposed to users who had read only access to Kuberentes Pods. This could allow users with just read-only access to perform actions that were only available to running tasks via Task SDK and potentially allow to modify state of Airflow Database for tasks.
