Looking like v8 now:

cnquery run terraform plan /home/christian/workspace/mondoo/github.com/cnquery/providers/terraform/provider/testdata/tfplan/plan_gcp_simple.json -c "terraform.settings{*}"
→ loaded configuration from /etc/opt/mondoo/mondoo.yml using source default
terraform.settings: {
  requiredProviders: []
  block: null
}
