| Titre | Chess.com Chess - Play and Learn (Android) 4.9.42 Information Disclosure |
|---|
| Description | A 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. |
