CVE-2026-33685: AVideo Allows Unauthenticated Access to AD_Server reports.json.php that Exposes Ad Campaign Analytics and User Data

The plugin/AD_Server/reports.json.php endpoint performs no authentication or authorization checks, allowing any unauthenticated attacker to extract ad campaign analytics data including video titles, user channel names, user IDs, ad campaign names, and impression/click counts. The HTML counterpart (reports.php) and CSV export (getCSV.php) both correctly enforce User::isAdmin(), but the JSON API was left unprotected.
