I understand what is an intent redirection vulnerability issue. Also, aware of the solutions. But I am facing trouble finding the origin of this issue. Play console is reporting that the error lies here androidx.fragment.app.FragmentActivity.startActivityForResult
.
I am using AppcompactActivity throughout the app. So I have checked every startActivityForResult in my app. None of them are forwarding an unsafe intent. I think this is from some third-party library, I am using many of them. Play console is not giving me much information. So I am unable to find the root of this security threat.
Are there any tools/methods to trace the intent redirection vulnerability issue? Especially if it is originating from a third-party library, how can we trace it? After applying the fix, how can we ensure the issue is resolved before submitting it to the Play-console?
