Description Adam Mariš 2016-05-05 14:58:09 UTC
It was reported that access to create STI builds is not tightly controlled. STI build has access to the docker socket and regular users are allowed to update pods and change the container image. This can result into regular user creating STI build and updating the pod to run evil image effectively taking control of the node.
