RISK

Why proxmox_configure_cloudinit_advanced is rated Medium

This tool modifies VM configuration through CloudInit settings, which is a reversible write operation. The severity is high because misconfigured CloudInit settings could cause VMs to fail to boot properly, expose credentials if improperly configured, or affect multiple VMs if applied broadly.
