Vulnerability details

The vulnerability allows a remote user to access and misuse execution API capabilities.

The vulnerability exists due to exposure of sensitive information in KubernetesExecutor when exposing worker pod JWT tokens in command-line arguments visible through pod metadata. A remote user can read pod details to harvest a JWT token and call state-mutating execution API endpoints to access and misuse execution API capabilities.

Exploitation requires an authenticated UI or API account and Kubernetes read-only access such as permission to view pod details in the Airflow namespace. Only deployments using the KubernetesExecutor are affected.
