CVE-2026-33761Public exploitNetwork attack vector

Unauthenticated Scheduler data disclosure via unchecked list endpoints

Published Mar 27, 2026 · Updated Mar 27, 2026

Missing authorization in WWBN AVideo 26.0 and earlier allows remote attackers to read Scheduler plugin data through three GET endpoints. The Scheduler_commands, Emails_messages, and Email_to_user list.json.php handlers call getAll() and serialize complete database tables without first invoking User::isAdmin(). No session or token is required, exposing internal callback URLs and parameters, administrator-written email content, and user-to-message targeting mappings.
