The manipulation leads to improper export of android application components. Attacking locally is a requirement. Upgrading to version 1.1.5 is able to address this issue. The name of the patch is 5423dcb0cd3e4d573b5520a71fa08aa279e4c3c7. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-259508."

Mitigation
Strategy: Attack Surface Reduction
If they do not need to be shared by other applications, explicitly mark components with android:exported="false" in the application manifest.
Mitigation
Strategy: Attack Surface Reduction
If you only intend to use exported components between related apps under your control, use android:protectionLevel="signature" in the xml manifest to restrict access to applications signed by you.
Mitigation
Strategy: Attack Surface Reduction
