CVE-2026-33478Public exploitNetwork attack vector

Unauthenticated command execution via clone-key disclosure and rsync

Published Mar 23, 2026 · Updated Mar 23, 2026

Command injection in World Wide Broadcast Network AVideo 26.0 and earlier allows remote attackers to execute commands through CloneSite. The unauthenticated clones.json.php endpoint returns clone keys, cloneServer.json.php accepts a stolen key to create a downloadable database dump, and cloneClient.json.php interpolates a server-supplied videosDir value into an rsync shell command without neutralizing metacharacters. No prior access or user interaction is required; successful chaining discloses the database and executes commands as the web-server user.
