AVideo Allows Unauthenticated Access to AD_Server reports.json.php that Exposes Ad Campaign Analytics and User Data

WWBN AVideo is an open source video platform. In versions up to and including 26.0, 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. Commit daca4ffb1ce19643eecaa044362c41ac2ce45dde contains a patch.
