CVE-2026-92172
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-92172 is a high-severity Improper Restriction of Communication Channel to Intended Endpoints (CWE-923) vulnerability in Facebook (inferred from references). Its CVSS base score is 8.8 (High).
Operationally, ranked at the 19th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-3 (Device Identification and Authentication) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Vulnerability Data
Prior to v66.0.0.733.524 of Meta Horizon OS, OVRMediaService could be induced to send a privileged PendingIntent including a com.oculus.horizon CallerIdentity to an arbitrary application registering for com.oculus.systemactivities.SCREENSHOT via a broadcast receiver. That would allow the application to impersonate the com.oculus.horizon…

Mitigating Controls (NIST 800-53 r5) AI
Requires unique identification and authentication of devices before establishing a communications session.
Enforces authenticity of communication sessions so the system only exchanges data with verified intended endpoints.
Protects transmitted information with cryptographic integrity mechanisms that implicitly verify endpoint identity.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Documenting authorized flows helps define intended endpoints but does not enforce channel restrictions at runtime.
Authenticating services/hardware directly prevents communication with unintended endpoints.
Protecting identity assertions supports endpoint verification but is narrower than channel restriction.
Data-in-transit protections commonly include certificate-based endpoint authentication to ensure correct peers.
Network segmentation and access controls directly enforce communication only with intended endpoints.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Network security controls directly enforce endpoint validation and channel restrictions.
A.8.21 mandates identifying/implementing network service security features (authentication, encryption, connection controls, authorization, monitoring, allowed endpoints via rules) and ensuring providers do so, which stops most improper-restriction cases from being exploitable; the bounded remainder is product-level endpoint validation logic (e.g. cert pinning, strict hostname checks) that lives in code rather than in service configuration or provider agreement.
Cryptography can protect channels but does not guarantee correct endpoint identity without additional controls.
Application security requirements may specify endpoint validation but do not implement it.
A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, assume-breach, never-trust/always-verify, end-to-end encryption, dynamic access control) plus design reviews that can stop many channel-misrouting flaws at source, but leaves a bounded remainder (e.g. flawed protocol selection or implementation bugs in the chosen channel that still reach the wrong endpoint).
Secure coding practices can implement endpoint checks but the control itself is process-oriented.
