Privileged PendingIntent in Meta Horizon OS

Publication date: 2026-09-30

Last updated on: 2026-09-30

Assigner: Facebook, Inc.

Description

Prior to v74.0.0.878.1682 of Meta Horizon OS, MediaSyncJobReceiver could be induced to send a privileged PendingIntent including a com.oculus.vrshell CallerIdentity to an arbitrary application listening via NotificationListenerService. That would allow the application to impersonate the com.oculus.vrshell package, as well as packages signed with the same key, towards any endpoint within the OS that uses CallerIdentity authentication.

Attack-Flow Graph

Executive Summary

This vulnerability involves a flaw in Meta Horizon OS before version 74.0.0.878.1682 where MediaSyncJobReceiver could be tricked into sending a privileged PendingIntent with a CallerIdentity to any app using NotificationListenerService. This allows the receiving app to impersonate com.oculus.vrshell or apps signed with the same key, bypassing authentication in systems relying on CallerIdentity.

Detection Guidance

Detection requires checking for unauthorized PendingIntent usage or impersonation attempts by applications with CallerIdentity authentication. Review installed apps for unexpected permissions or behaviors related to com.oculus.vrshell. Check system logs for suspicious NotificationListenerService interactions.

Impact Analysis

An attacker could exploit this to impersonate legitimate apps, gaining unauthorized access to sensitive data or functions within the OS. This could lead to data theft, privilege escalation, or control over the device depending on the impersonated app's permissions.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or health data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations using affected versions may face compliance violations and legal consequences.

Mitigation Strategies

Update Meta Horizon OS to version v74.0.0.878.1682 or later to address the PendingIntent and CallerIdentity issue.
