CVE-2026-0842Public exploit

Unauthorized image display via unauthenticated BLE writes

Published Jan 11, 2026 · Updated Jan 11, 2026

Missing authentication in Flycatcher Inc. smART Sketcher 2.0 allows physically proximate attackers to display arbitrary images over Bluetooth. The Bluetooth Low Energy interface accepts an image-transfer command and RGB565 image chunks through its writable GATT characteristic without authenticating the connected client. Exploitation requires Bluetooth range and a powered, otherwise unoccupied projector; it changes the projected image but establishes no broader device control.
