Key facts

CVE-2026-71278 is a Critical (9.8) vulnerability: rust-iot-platform allows creating a "calc rule" via POST /calc-rule/create…. This entry ships a detection-only PoC and a Docker test lab.


CVE	CVE-2026-71278
Severity	Critical (9.8)
Detection / prevention	—
PoC	poc.py
Source	2026/CVE-2026-71278/

Details¶

English | 한국어

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.
