- Add 60 req/min throttle to the public API group and a stricter 10 req/min
throttle to POST /highscores.
- Replace mass-assigned $guarded=[] with explicit $fillable on User, Meetup,
Course, Lecturer, and SelfHostedService. created_by stays out of the
whitelist; the existing creating() hooks continue to populate it.
- Require authenticated user on Api/MeetupController::index instead of
trusting the user_id query parameter (IDOR).
- Constrain the /img and /img-public route paths to a safe character set
and reject any path containing ".." in ImageController.
- Add rel="noopener noreferrer" to every target="_blank" link on the meetup
and course landing pages.
