Unauthenticated code execution via oversized HTTP body
Published Jun 14, 2026 · Updated Jun 14, 2026
Buffer overflow in the GALAYOU Y4 1.0.0 web server allows remote attackers on the local network to execute arbitrary code. The HTTP request parser trusts a client-supplied Content-Length and copies the POST body into a fixed-size stack buffer without a bounds check. No authentication or user interaction is required; a crafted request can overwrite control data and run commands on the camera.
