| Title | Groww Groww Android Application Latest Available Version Weak Client-Side Protection and Unsafe WebView URL Handling |
|---|
| Description | The Groww Android application contains an internal WebView activity that can be invoked in a privileged ADB/debug environment. During testing, arbitrary external URLs could be rendered inside the application WebView, and JavaScript execution within the trusted application context was confirmed using a controlled demonstration environment.
Additionally, weak enforcement of the client-side application lock allowed navigation into portions of the application interface without passcode re-validation after activity invocation.
The issue requires privileged device access (ADB/debug environment) and does not result in server-side authentication bypass or direct account compromise.
Security Impact:
Rendering of attacker-controlled content inside application WebView
Potential UI redressing or phishing-style abuse under privileged device conditions
Weak local app-lock enforcement
Attack Requirements:
Physical/debug access to device
ADB-enabled environment
