Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Prior to 1.1.5 and 1.0.2, there is a nil pointer dereference vulnerability in the Omni Resource Service allows unauthenticated users to cause a server panic and denial of service by sending empty create/update resource requests through the API endpoints. The vulnerability exists in the isSensitiveSpec function which calls grpcomni.CreateResource without checking if the resource's metadata field is nil. When a resource is created with an empty Metadata field, the CreateResource function attempts to access resource.Metadata.Version causing a segmentation fault. This vulnerability is fixed in 1.1.5 and 1.0.2.

Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Prior to version 0.48.0, Omni Wireguard SideroLink has the potential to escape. Omni and each Talos machine establish a peer-to-peer (P2P) SideroLink connection using WireGuard to mutually authenticate and authorize access. The WireGuard interface on Omni is configured to ensure that the source IP address of an incoming packet matches the IPv6 address assigned to the Talos peer. However, it performs no validation on the packet's destination address. The Talos end of the SideroLink connection cannot be considered a trusted environment. Workloads running on Kubernetes, especially those configured with host networking, could gain direct access to this link. Therefore, a malicious workload could theoretically send arbitrary packets over the SideroLink interface. This issue has been patched in version 0.48.0.
