The Joyland AI app accepts invalid SSL certificates in the invisible advertisement WebView by default.

Joyland AI app explicitly permits cleartext HTTP traffic on Android 9+ where the default is to block it.

Joyland AI app allows an attacker with shared network access to inject JavaScript into content loaded in WebView. Without user-granted permissions, an attacker could access the clipboard, make arbitrary HTTP requests via the Weex 'stream' module, or access app-internal storage. If the installed app has been granted permissions previously, the attacker can access the entire file system, camera, microphone, and GPS tracking.

The Joyland AI app contains hard-coded credentials for the GeTui push notification service, allowing an attacker to access the GeTui REST API and send push notifications containing arbitrary content to any user, group of users, or all users of the app at once.
