CVE-2026-86553: Improper privilege management vulnerability

SmartLife app dynamically generates fresh SmartLife application authentication parameters inside its runtime process. Using the acquired SmartLife application authentication parameters, an attacker can directly call the backend interface /account/verify.serv to obtain the real account ID corresponding to a registered email address. By spoofing the application authentication information together with the target account ID, the attacker can reset the password of the target account.
