MobSF Broadcast Receiver Issue

Permission: com.google.android.c2dm.permission.SEND [android:exported=true]

A Broadcast Receiver is found to be shared with other apps on the device therefore
leaving it accessible to any other application on the device. 
It is protected by a permission which is not defined in the analysed application. 
As a result, the protection level of the permission should be checked where it is 
defined. If it is set to normal or dangerous, a malicious application can request 
and obtain the permission and interact with the component. If it is set to signature, 
only applications signed with the same certificate can obtain the permission.
