CVE-2026-7703Public exploitNetwork attack vector

Unauthenticated command execution via WebSocket API

Published May 3, 2026 · Updated May 3, 2026

Code injection in AV Stumpfl PIXERA two 25.2 R2 allows remote attackers to execute arbitrary commands through the WebSocket API. The API handler accepts an attacker-selected operation address and parameters over a WebSocket and dispatches the request without authentication or input neutralization. Port 1338 is open by default, so any network-reachable attacker can run commands and modify files on the media server.
