A user can create a project named "myProject", use that project for a while and then delete it. After the original project is deleted, another user can create a project called "myProject". Since the subjectaccessreview will now pass for this second user, they will be able to access metrics from the original project.

An input validation flaw was found in the way OpenShift 3 handles requests for images. A user, with a copy of the manifest associated with an image, can pull an image even if they do not have access to the image normally, resulting in the disclosure of any information contained within the image.

Kubernetes in OpenShift3 allows remote authenticated users to use the private images of other users should they know the name of said image.
