CVE-2026-54144 Details
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.
A vulnerability in the OpenHuman desktop application and Rust library, prior to version 0.56.0 on macOS, allows injected JavaScript in embedded webviews, such as Google Meet, to call 'getDisplayMedia' without user interaction. This omission of a required gesture bypasses standard browser permissions, enabling unauthorized capture of the user's desktop. The captured stream can include sensitive information such as chats, documents, source code, emails, meeting content, and credentials. The issue arises because the embedded Chromium environment automatically selects the primary display for capture, without the usual user prompt, if OpenHuman has been granted screen recording permissions.
Users can update to OpenHuman version 0.56.0 or later, where this vulnerability has been fixed.
