CVE-2026-33761: AVideo: Unauthenticated Access to Scheduler Plugin Endpoints Leaks Scheduled Tasks, Email Content, and User Mappings

Three list.json.php endpoints in the Scheduler plugin lack any authentication check, while every other endpoint in the same plugin directories (add.json.php, delete.json.php, index.php) requires User::isAdmin(). An unauthenticated attacker can retrieve all scheduled tasks (including internal callback URLs and parameters), admin-composed email messages, and user-to-email targeting mappings by sending simple GET requests.
