High Clear text traffic is Enabled For App[android:usesCleartextTraffic=true]
The app intends to use cleartext network traffic, such as cleartext HTTP, FTP stacks, DownloadManager, and MediaPlayer. The default value for apps that target API level 27 or lower is "true". Apps that target API level 28 or higher default to "false". The key reason for avoiding cleartext traffic is the lack of confidentiality, authenticity, and protections against tampering; a network attacker can eavesdrop on transmitted data and also modify it without being detected.
Low App has a Network Security Configuration[android:networkSecurityConfig=@xml/network_security_config]
The Network Security Configuration feature lets apps customize their network security settings in a safe, declarative configuration file without modifying app code. These settings can be configured for specific domains and for a specific app.
High Debug Enabled For App[android:debuggable=true]
Debugging was enabled on the app which makes it easier for reverse engineers to hook a debugger to it. This allows dumping a stack trace and accessing debugging helper classes.
Medium Application Data can be Backed up[android:allowBackup=true]
This flag allows anyone to backup your application data via adb. It allows users who have enabled USB debugging to copy application data off of the device.
High Broadcast Receiver (trust.weasel.SmsBroadcast) is Protected by a permission, but the protection level of the permission should be checked.
Permission: android.permission.BROADCAST_SMS [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.

High Launch Mode of Activity (trust.weasel.InjectCC) is not standard.
An Activity should not be having the launch mode attribute set to "singleTask/singleInstance" as it becomes root Activity and it is possible for other applications to read the contents of the calling Intent. So it is required to use the "standard" launch mode attribute when sensitive information is included in an Intent.
