Default access permissions for Persistent Volumes (PVs) created by the Kubernetes Azure cloud provider in versions 1.6.0 to 1.6.5 are set to "container" which exposes a URI that can be accessed without authentication on the public internet. Access to the URI string requires privileged access to the Kubernetes cluster or authenticated access to the Azure portal.
Kubernetes version 1.5.0-1.5.4 is vulnerable to a privilege escalation in the PodSecurityPolicy admission plugin resulting in the ability to make use of any existing PodSecurityPolicy object.
Openshift allows remote attackers to gain privileges by updating a build configuration that was created with an allowed type to a type that is not allowed.
The API server in Kubernetes does not properly check admission control, which allows remote authenticated users to access additional resources via a crafted patched object.
