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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.1,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1793912294948,"publishedAt":1793895286830,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/tinyhumansai/openhuman/security/advisories/GHSA-936r-hw6f-jjf2"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tinyhumansai/openhuman/pull/2636"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tinyhumansai/openhuman/commit/60050aa09a870f53ed7e4cd40ed41fd2860329e7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tinyhumansai/openhuman/releases/tag/v0.56.0"}],"remediation":[],"revision":"fd22ae144f635487325557d10838f37004817f3f2f6a9b6a2977014fb82c039b","sources":[{"modifiedAt":1793912294948,"name":"CNA: GitHub_M","retrievedAt":1793913845210,"url":"https://www.cve.org/CVERecord?id=CVE-2026-54144"}],"ssvc":{"assessedAt":1793912287169,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"OpenHuman: Embedded Google Meet webview can silently capture the macOS desktop without a user gesture","updatedAt":1793913845210}
