{"id":"CVE-2026-54144","summary":"OpenHuman: Embedded Google Meet webview can silently capture the macOS desktop without a user gesture","details":"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.","aliases":["GHSA-936r-hw6f-jjf2"],"modified":"2026-11-05T21:32:30.145417400Z","published":"2026-11-05T16:14:46.830Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-285","CWE-359"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54144.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54144.json"},{"type":"FIX","url":"https://github.com/tinyhumansai/openhuman/commit/60050aa09a870f53ed7e4cd40ed41fd2860329e7"},{"type":"FIX","url":"https://github.com/tinyhumansai/openhuman/pull/2636"},{"type":"WEB","url":"https://github.com/tinyhumansai/openhuman/releases/tag/v0.56.0"},{"type":"ADVISORY","url":"https://github.com/tinyhumansai/openhuman/security/advisories/GHSA-936r-hw6f-jjf2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54144"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tinyhumansai/openhuman","events":[{"introduced":"0"},{"fixed":"e8968077aeb5c6a687d52f3f58474363c2f3f7ed"},{"fixed":"60050aa09a870f53ed7e4cd40ed41fd2860329e7"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"0.56.0"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"fixed":"60050aa09a870f53ed7e4cd40ed41fd2860329e7"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_TAG","original_tag":"v0.56.0","range":[{"fixed":"e8968077aeb5c6a687d52f3f58474363c2f3f7ed"}]}]}}],"versions":["v0.54.0","v0.53.51-staging","v0.53.50-staging","v0.53.49-staging","v0.53.48-staging","v0.53.47-staging","v0.53.46-staging","v0.53.45-staging","v0.53.44-staging","v0.53.43","v0.53.40","v0.53.38-staging","v0.53.36-staging","v0.53.35-staging","v0.53.35","v0.53.31-staging","v0.53.30-staging","v0.53.29-staging","v0.53.28-staging","v0.53.27-staging","v0.53.26-staging","v0.53.25-staging","v0.53.22","v0.53.20-staging","v0.53.19-staging","v0.53.17","v0.53.16","v0.53.15-staging","v0.53.15","v0.53.14-staging","v0.53.13-staging","v0.53.12-staging","v0.53.11-staging","v0.53.10-staging","v0.53.6-staging","v0.53.5-staging","v0.53.4","v0.53.3","v0.53.1","v0.53.0","v0.52.28","v0.52.27","v0.52.26","v0.52.20","v0.52.19","v0.52.18","v0.52.17","v0.52.16","v0.52.15","v0.52.12","v0.52.9","v0.52.7","v0.52.6","v0.52.2","v0.52.0","v0.51.19","v0.51.18","v0.51.17","v0.51.8","v0.51.6","v0.51.5","v0.51.4","v0.51.2","v0.50.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54144.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N"}]}
