CVE-2026-45578Public exploitNetwork attack vector

Authenticated command execution via unescaped live stream key

Published May 29, 2026 · Updated May 29, 2026

OS command injection in WWBN AVideo 29.0 and earlier allows remote authenticated users to execute commands through a crafted live stream key. The YPTSocket branch in plugin/Live/on_publish.php concatenates three values into an execAsync shell command, surrounding them with literal single quotes instead of escaping them. A canStream account, enabled Live and YPTSocket plugins, and network access to the endpoint are required; injected commands run as the web-server user.
