The com.callassistant.android (aka AI Call Assistant & Screener) application 1.174 for Android enables any installed application (with no permissions) to place phone calls without user interaction by sending a crafted intent via the com.callassistant.android.ui.call.incall.InCallActivity component.
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
