CVE-2024-3744

Token disclosure via unsanitized gRPC request logging

Published May 15, 2024 · Updated Feb 13, 2025

Sensitive information exposure in Kubernetes Azure File CSI Driver 1.29.3 and earlier and 1.30.0 allows local users to read service account tokens. The logGRPC interceptor sanitizes gRPC requests without removing csi.storage.k8s.io/serviceAccount.tokens from volume_context, then writes the request to the driver log. Exposure requires TokenRequests, driver verbosity of 2 or higher, and driver-log access; disclosed tokens can grant access to cloud-vault secrets.
