## Technical details

The MediaSyncJobReceiver component in Meta Horizon OS prior to v74.0.0.878.1682 can be induced to send a privileged PendingIntent containing com.oculus.vrshell CallerIdentity to arbitrary applications listening via NotificationListenerService. This allows an attacker to impersonate the vrshell package and other similarly-signed packages, bypassing CallerIdentity-based authentication checks within the OS. The vulnerability requires local access and does not involve remote network exploitation.
