Summary

OpenHuman before 0.56.0 on macOS lets page JavaScript in a supported remote account webview, such as Google Meet, call getDisplayMedia without a user gesture (CWE-285). The request is not rejected and the embedded Chromium environment captures the primary display automatically. An attacker with JavaScript execution in an allowed embedded origin can capture the desktop when OpenHuman already has Screen Recording permission, exposing chats, documents, source code, email and credentials.

Description from the CNA

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.
