### Official description

Snipe-IT is an IT asset/license management system. Prior to 8.6.3, any activated account can request /maintenances/{id} and read maintenance records for assets in the same company without asset or maintenance permission. app/Http/Controllers/MaintenancesController.php show() renders the record without authorize(), while company-scoped route-model binding only prevents access to other companies.
