Apache Cordova Android versions 3.6.4 and below use a bridge that allows the Native Application to communicate with the HTML and Javascript that control the user interface. To protect this bridge on Android, the framework uses a BridgeSecret to protect it from third-party hijacking. However, the BridgeSecret is not sufficiently random and can be determined in certain scenarios.
