CVE-2026-86554 (GCVE-0-2026-86554)

Vulnerability from cvelistv5 – Published: 2026-09-20 07:55 – Updated: 2026-09-20 09:17

Title

Email enumeration and account ID leakage vulnerabilities in ZTE SmartLife APP

Summary

SmartLife app dynamically generates brand‑new SmartLife application authentication parameters within its runtime process. With the obtained SmartLife application authentication parameters, attackers can directly invoke the backend interface /account/verify.serv to determine whether a target email address is registered for a SmartLife account. If the account exists, the real backend account ID can also be retrieved.

Severity

4.3 (Medium)
