Technical details
The vulnerability stems from the SmartLife app's runtime generation of authentication parameters without proper obfuscation or server-side validation. Attackers can intercept or reverse-engineer these authentication credentials, then invoke the /account/verify.serv backend endpoint to enumerate valid email addresses and retrieve backend account IDs. This is an information disclosure vulnerability requiring network access and knowledge of the authentication scheme.
