A LAN-adjacent attacker can connect to the exposed WebDriver service to execute arbitrary JavaScript, read and exfiltrate sensitive localStorage data including ACR telemetry, MAC addresses, ad-service credentials, and location data, inject persistent content onto the display, and access the window.hisense native bridge to perform filesystem read/write and system-state operations.","published":"2026-11-06T19:17:44.550","modified":"2026-11-06T19:17:44.550","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/yehia-mamdouh/Hisense-Smart-TV-Security-Research"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/hisense-vidaa-smart-tv-unauthenticated-webdriver-remote-access"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-06T19:17:44.550"}}
