Title
Unauthorized inventory stock manipulation via unlocked variant property in VariantStock component
Description
A lack of authorization control was discovered in the stockAction() method in packages/admin/src/Livewire/Components/Products/VariantStock.php. The component exposes a public $variant property without the #[Locked] attribute, so the variant ID is client-mutable via the Livewire wire payload. The stockAction() returns an Action with no ->authorize(...) chain, meaning any authenticated admin-panel session, including browse-only staff who hold zero edit permissions, can call this action to adjust inventory levels for any product variant. The combination of missing authorization and an unlocked model binding lets the attacker both bypass the permission gate and redirect the mutation to an arbitrary variant in the database.
