CVE-2026-54144CVE-2026-54144

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 i
