CVE-2026-33651: fallo de gravedad alta en WWBN AVideo

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `remindMe.json.php` endpoint passes `$_REQUEST['live_schedule_id']` through multiple functions without sanitization until it reaches `Scheduler_commands::getAllActiveOrToRepeat()`, which directly concatenates it into a SQL `LIKE` clause. Although intermediate functions (`new Live_schedule()`, `getUsers_idOrCompany()`) apply `intval()` internally, they do so on local copies within `ObjectYPT::getFromDb()`, leaving the original tainted variable unchanged. Any authenticated user can perform time-based blind SQL injection to extract arbitrary database contents. Commit 75d45780728294ededa1e3f842f95295d3e7d144 contains a patch.
