Medium (6.9) in kubevirt kubevirt. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in kubevirt.io/kubevirt 1.7.0.
KubeVirt is a virtual machine management add-on for Kubernetes. In 1.5.0 and earlier, the permissions granted to the virt-handler service account, such as the ability to update VMI and patch nodes, could be abused to force a VMI migration to an attacker-controlled node. This vulnerability could otherwise allow an attacker to mark all nodes as unschedulable, potentially forcing the migration or creation of privileged pods onto a compromised node.
