CVE-2026-102667 · Severity: high · CVSS 8.3 · Published 2026-10-01

Joyland AI is a mobile application that allows users to interact with an AI chatbot. An attacker with access to the same network can inject malicious JavaScript code into content displayed in the app's WebView, potentially stealing clipboard data, making unauthorized HTTP requests, and accessing app storage. If the app has been granted permissions by the user, attackers can additionally access the device's files, camera, microphone, and GPS location.

## Technical details

The vulnerability stems from improper WebView configuration that allows JavaScript injection via network-based attacks. An attacker on the same network can exploit the Weex 'stream' module and WebView implementation to execute arbitrary JavaScript without initial user permissions; if permissions have been previously granted, the full extent of device capabilities becomes accessible. There is no known fix available for this vulnerability.
