CVE-2026-71278
rust-iot-platform Unauthenticated Remote Code Execution via Unsandboxed Calc-Rule Script Evaluation
Description

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.

CVSS 3.1 CRITICAL 309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c
Solution
Enforce authentication for calc rule creation and sanitize script input.
  • Implement authentication for the POST /calc-rule/create endpoint.
  • Sanitize or sandbox arbitrary script execution.
  • Update the application to the latest version.
  • Review other API endpoints for similar issues.
