## The Core Issue

A code injection in the `create_user` API call allows any abritrary code to be injected, alongside achieving a full remote shell that, if the provider runs CloudLinux, escapes the CloudLinux jail entirely due to how UAPI runs and is executed. This can be chained with other vulnerabilities such as CVE-2026-29201 for full system takeover.
