An issue was discovered in Kata Containers through 1.11.3 and 2.x through 2.0-rc1. The runtime will execute binaries given using annotations without any kind of validation. Someone who is granted access rights to a cluster will be able to have kata-runtime execute arbitrary binaries as root on the worker nodes.
