CVE-2026-82989Public exploitNetwork attack vector

Unauthenticated display control via exposed key-event socket

Published Oct 5, 2026 · Updated Oct 5, 2026

Input injection in ViewSonic vCast 3.2.715 and earlier allows remote attackers to send unauthorized key events to ViewBoard displays. The ViewBoard receiver's exposed control socket accepts plaintext KEYEVENT codes without checking authentication and translates them into Android key presses. Network access to the display is required; the injected input can also confirm an installation prompt when chained with the separate APK-download flaw.
