Prior to version 4.0.0, kata-runtime is vulnerable to host code execution via an unvalidated configuration path annotation. The runtime accepts an arbitrary io.katacontainers.config_path pod annotation and loads the referenced host TOML file without restriction. As a result, a pod user who can place a file at a host-visible path can supply a configuration that selects an attacker-controlled hypervisor or virtio-fs daemon binary, executing code as root on the host.
