Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference via the isSensitiveSpec() function which calls grpcomni.CreateResource without checking if the resource's metadata field is nil. An attacker can cause a server crash and disrupt service availability by sending empty resource creation or update requests to the affected API endpoints.
