8.0 highCVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:HCVE-2023-1260
High (8.0). EPSS 1.6% chance of exploitation in the next 30 days. Fixed in github.com/openshift/apiserver-library-go 0.0.0-20230621.
An authentication bypass vulnerability was discovered in kube-apiserver. This issue could allow a remote, authenticated attacker who has been given permissions "update, patch" the "pods/ephemeralcontainers" subresource beyond what the default is. They would then need to create a new pod or patch one that they already have access to. This might allow evasion of SCC admission restrictions, thereby gaining control of a privileged pod.
