CVE-2026-92172 · Severity: info · Published 2026-09-30

Meta Horizon OS (the operating system for Meta Quest headsets) contains a flaw in the OVRMediaService component that allows a malicious app to impersonate a system service and gain unauthorized access. An attacker could create an app that tricks the system into granting it elevated permissions, potentially allowing it to access sensitive functionality that should only be available to trusted system components. This affects Horizon OS versions prior to 66.0.0.733.524.

## Technical details

OVRMediaService sends a privileged PendingIntent containing com.oculus.horizon CallerIdentity credentials to arbitrary apps that register a broadcast receiver for com.oculus.systemactivities.SCREENSHOT. An attacker can register for this broadcast and intercept the intent to obtain a forged CallerIdentity, enabling impersonation of the com.oculus.horizon package for authentication bypass against endpoints using CallerIdentity verification. Local attack vector; requires malicious app installation.
