Multiple critical security vulnerabilities have been identified across container storage module components, including severe authentication bypasses, improper authorization, hard-coded credentials, and privilege escalation vectors. Evaluated at maximum severity with CVSS scores reaching up to 10.0, these flaws permit unauthenticated remote attackers to compromise backend storage layer infrastructure completely. Exploitation of these vulnerabilities risks unauthorized exposure and manipulation of administrator credentials, arbitrary cluster node control, and widespread cross-tenant access. Immediate application of vendor-provided software updates is necessary to secure persistent storage frameworks and prevent total infrastructure compromise.
CVE-2026-46595: Improper authorization flaw in the authorization server holding a CVSS score of 10.0. The vulnerability resides within authorization control components and permits unauthenticated remote attackers to gain unauthorized control over storage layers. Exploitation allows full administrative manipulation of storage infrastructure across connected systems.[/subscribe_to_unlock_form]

CVE-2026-39821: Input validation issue in the IDNA net library component assigned a CVSS score of 10.0. The flaw stems from improper handling of Punycode-encoded labels in network protocol handling. Unauthenticated remote attackers can exploit this to disrupt core network services or cause application failure across dependent storage modules.
CVE-2024-45337: Authorization bypass vulnerability with a CVSS score of 9.1 within connection authentication interfaces. The bug resides in connection server authentication procedures, permitting remote attackers to bypass authorization controls. Successful exploitation results in unauthorized access to restricted backend services and resources.
CVE-2026-39830: Resource lock management vulnerability assigned a CVSS score of 9.1 affecting server communication channels. The defect allows remote client connections to trigger unexpected deadlock conditions on backend servers. Exploitation results in permanent denial-of-service conditions across storage proxy services.
CVE-2026-39831: Missing authorization check rated with a CVSS score of 9.1 located within core access control handlers. The vulnerability allows unauthorized actors to execute privileged functions without proper validation. Exploitation risks unauthorized modification and exposure of underlying storage configurations.
CVE-2026-39832: Deserialization of untrusted data holding a CVSS score of 9.1 inside data processing services. The issue permits remote attackers to supply malformed serialized objects during request processing. Successful exploitation can lead to arbitrary code execution within the storage management layer.
CVE-2026-39833: Missing authorization defect with a CVSS score of 9.1 within management administrative interfaces. The vulnerability allows unauthenticated remote requests to bypass access restriction logic entirely. Attackers exploiting this flaw gain unauthorized elevated command capabilities across administrative endpoints.
CVE-2026-39834: Integer overflow vulnerability assigned a CVSS score of 9.1 within memory calculation routines. The bug occurs during processing of oversized input payloads in internal storage components. Exploitation can trigger memory corruption, system instability, or potential arbitrary execution.
CVE-2026-63688: Critical credential exposure flaw with a CVSS score of 10.0 in the gRPC authorization server component. The issue allows remote attackers to obtain plaintext administrator credentials for registered storage arrays. Exploitation provides full administrative takeover spanning all connected storage infrastructure product families.
CVE-2026-63692: Authentication bypass vulnerability scoring 10.0 within the authorization proxy and tenant management service. The defect enables total bypass of login verification procedures for unauthenticated remote actors. Exploitation grants unauthorized access to read and modify storage resources across all registered tenant environments.
CVE-2026-67269: Privilege escalation defect evaluated at a CVSS score of 9.9 in the custom resource reconciler component. The vulnerability allows low-privileged local users to achieve root-level execution on underlying cluster nodes. Exploitation enables total host node compromise via a single custom resource submission.
CVE-2026-67273: Template engine rendering vulnerability with a CVSS score of 9.6 in cluster management operator modules. The defect exposes sensitive internal variable rendering routines to unauthorized access. Exploitation enables cluster-wide read access to confidential Kubernetes Secrets.
CVE-2026-54472: Hard-coded credential flaw scoring 9.8 within token generation routines. The issue allows remote attackers to leverage static cryptographic elements to forge valid administrator access tokens. Exploitation grants persistent, full administrative access to protected storage services.
CVE-2026-61421: Hard-coded signing secret vulnerability evaluated at a CVSS score of 9.8 in legacy authorization setups. The flaw allows remote attackers to forge JSON Web Tokens using publicly exposed signing keys. Exploitation yields unauthorized administrative impersonation across non-rotated deployments.
Organizations using affected container storage modules must immediately upgrade software installations to version 1.18.0 or later to remediate these critical threats. Because no functional workarounds are available, immediate deployment of the latest vendor security patches is required to prevent infrastructure takeover.
We recommend you to update Dell Container Storage Modules to version 1.18.0.
