TitelChess.com Chess - Play and Learn (Android) 4.9.42 Information Disclosure
BeschreibungA vulnerability in the Chess.com Android application (com.chess) allows a local attacker with physical device access and USB debugging enabled to extract sensitive authentication data via ADB backup. The application sets android:allowBackup="true" in AndroidManifest.xml without backup exclusion rules, permitting full data directory extraction without root access. A Google OAuth ID Token (JWT) is stored in plaintext within shared_preferences/ com.chess.app.login_credentials.xml. The extracted token exposes verified user identity claims including email address, full name, profile picture URL, and Google subject identifier (sub). CWE-312/CWE-530/CWE-922.
