# CVE-2026-54144: OpenHuman: Embedded Google Meet webview can silently capture the macOS desktop without a user gesture

- Also known as: EUVD-2026-117578
- Severity: CVSS 6.1 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 0.56.0

CVE-2026-54144 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.1 (medium) and affects openhuman; fixed in 0.56.0.

## Summary

OpenHuman's embedded Google Meet webview on macOS can let page JavaScript capture the whole desktop without a fresh user gesture, if the app already has Screen Recording permission. An attacker who can run JavaScript in an allowed embedded origin can exploit this remotely, without logging in, to get a live desktop capture that may expose chats, documents, source code, email, credentials, and one-time codes.

## Affected

- tinyhumansai openhuman: fixed in 0.56.0

## Description

OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before 0.56.0 on macOS, the runtime injected into a supported remote account webview such as Google Meet allows page JavaScript to call getDisplayMedia without a live user gesture. Instead of rejecting the request, the shim falls through to native Chromium capture behavior, and the embedded CEF environment can auto-select the primary display because it lacks the normal desktop-media picker. If OpenHuman already has macOS Screen Recording permission and an attacker obtains JavaScript execution in an allowed embedded origin, the attacker can obtain a real desktop capture stream without a new user gesture. The stream can expose chats, documents, source code, email, meeting content, credentials, one-time codes, and other visible desktop information. The separate direct screen_share_begin_session IPC path failing origin validation does not prevent exploitation through getDisplayMedia. This issue is fixed in version 0.56.0.
