Today i have received email like following,
Security alert
Your app includes a WebView that is vulnerable to JavaScript interface injection. Please see this Google Help Center article for details.
Vulnerable locations:
com.facebook.ads.internal.view.b.a->
com.facebook.ads.internal.view.m->c
Please fix the issue before: 03/27/2019
Any idea how to fix this issue?
Update:
I am using this sdk of facabook.
'com.facebook.android:audience-network-sdk:4.99.1'
The current version of the SDK is 5.1.0, you should upgrade: https://developers.facebook.com/docs/audience-network/download/
Date of the update: October 31, 2018
It should hopefully fix your issue. If that does not solve it, you could create a bug report so they include a fix in the next versions: https://developers.facebook.com/support/bugs/
