CVE-2025-5187
A vulnerability exists in the NodeRestriction admission controller in Kubernetes clusters where node users can delete their corresponding node object by patching themselves with an OwnerReference to a cluster-scoped resource.
Does this matter?
Lower severity and a low EPSS score (0.54%). Track it; it rarely justifies an emergency change on its own.
