Livewire PowerGrid: SQL Injection through the public `sortDirection` Livewire property in the `naturalSort` order-by path

Livewire PowerGrid creates data tables based on Laravel Livewire library. From version 6.0.0 to before version 6.10.4, the public Livewire property sortDirection is interpolated verbatim into a raw SQL ORDER BY clause and is not restricted to asc/desc, allowing arbitrary SQL injection through POST /livewire/update. This issue has been patched in version 6.10.4.
