Prior to version 5.16.1, the REST API's `AddonViewSet` (`weblate/api/views.py`, line 2831) uses `queryset = Addon.objects.all()` without overriding `get_queryset()` to scope results by user permissions. This allows any authenticated user (or anonymous users if `REQUIRE_LOGIN` is not set) to list and retrieve ALL addons across all projects and components via `GET /api/addons/` and `GET /api/addons/{id}/`.
