Incorrect Privilege Assignment

CWE-266

This application sends a special intent with a flag that allows the receiving application to read a data file for backup purposes.


               
sendBroadcast(intent);

               
}
}
stealUserData(userData);

Any malicious application can register to receive this intent. Because of the FLAG_GRANT_READ_URI_PERMISSION included with the intent, the malicious receiver code can read the user's data.
