CRITICAL 9.8EPSS 0.66%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.66%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

rust-iot-platform allows creating a "calc rule" via POST /calc-rule/create (api/src/controller/calc_rule_router.rs) containing an arbitrary field. This route does not take the AuthToken request guard used elsewhere in the application, making it reachable without authentication.
