Technical details
The csm-authorization-storage gRPC server lacks authentication checks for critical functions, allowing unauthenticated remote attackers to extract backend storage administrator credentials (CVE-2026-63688). Additional flaws include hard-coded credentials in CSM Authorization and csm-docs components, improper privilege management in the ContainerStorageModule Custom Resource reconciler, and certificate validation bypass in the proxy-server. These vulnerabilities require no user interaction and are remotely exploitable over the network.
