CVE-2026-86553

Estado: AplazadaAlta (8.8)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
