CVE-2026-32794Network attack vector

Credential interception via unverified Kubernetes TokenRequest TLS

Published Mar 30, 2026 · Updated Mar 30, 2026

Improper certificate validation in Apache Airflow Provider for Databricks 1.10.0 through 1.11.x allows attackers to intercept token exchange traffic. In DatabricksHook, synchronous requests set verify=False and asynchronous requests set ssl=False when calling the Kubernetes TokenRequest API, accepting an unverified API server certificate. The flaw is reachable only when federated_k8s authentication uses the TokenRequest method inside Kubernetes, enabling man-in-the-middle attackers with cluster-network access to read credentials or alter exchanged traffic.
