rust-iot-platform allows creating a "calc rule" via POST /calc-rule/create (api/src/controller/calc_rule_router.rs) containing an arbitrary script field. This route does not take the AuthToken request guard used elsewhere in the application, making it reachable without authentication. The stored script is subsequently executed via quick_js::Context::eval() in api/src/biz/calc_run_biz.rs with no sandboxing, allowing an unauthenticated attacker to achieve arbitrary JavaScript execution in the server process by creating and triggering a malicious calc rule.
