Summary

Prior to 9/18/2026, the iSteamX mobile application's AWS policy could grant authenticated users access to wildcard MQTT topics, which can expose other users' device data and allow the attacker to start and stop other connected users' devices. This risked exposing user profile information and potential scalding due to unintended device activation.
