CVE-2026-63688Network attack vectorHinoki check available

Credential disclosure via unauthenticated storage gRPC server

Published Oct 6, 2026 · Updated Oct 6, 2026

Missing authentication in Dell Container Storage Modules before 1.18.0 allows remote attackers to read storage administrator credentials via gRPC. The csm-authorization-storage gRPC server does not authenticate callers before granting access to credentials for registered storage arrays; Dell has not identified the affected RPC methods. Exploitation requires network reachability to the affected service, and the credential exposure extends to arrays registered with that deployment.
