{"id":"CVE-2026-54144","published":"2026-11-05T17:18:19.680","lastModified":"2026-11-05T21:18:51.123","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.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N","cwes":["CWE-285","CWE-359"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tinyhumansai/openhuman/commit/60050aa09a870f53ed7e4cd40ed41fd2860329e7","tags":[]},{"url":"https://github.com/tinyhumansai/openhuman/pull/2636","tags":[]},{"url":"https://github.com/tinyhumansai/openhuman/releases/tag/v0.56.0","tags":[]},{"url":"https://github.com/tinyhumansai/openhuman/security/advisories/GHSA-936r-hw6f-jjf2","tags":[]}],"exploitRefs":[{"url":"https://github.com/tinyhumansai/openhuman/commit/60050aa09a870f53ed7e4cd40ed41fd2860329e7","tags":[]},{"url":"https://github.com/tinyhumansai/openhuman/pull/2636","tags":[]},{"url":"https://github.com/tinyhumansai/openhuman/releases/tag/v0.56.0","tags":[]},{"url":"https://github.com/tinyhumansai/openhuman/security/advisories/GHSA-936r-hw6f-jjf2","tags":[]}],"hasPoc":true,"ai":null}
