Summary

Shopper is a Headless e-commerce Admin Panel. Prior to 2.10.0, the Variants Livewire component in `packages/admin/src/Livewire/Components/Products/Form/Variants.php` exposes `DeleteAction` and `DeleteBulkAction` without server-side authorization. An authenticated staff user with `edit_products` can access `/shopper/products/{id}/edit` and obtain the signed component state even without `delete_product_variants`. The `callTableAction` and `callTableBulkAction` paths then permanently delete individual or multiple variants without checking that dedicated permission. For variant products, this can destroy the sellable catalogue and disrupt storefront product pages, cart, and checkout. This issue is fixed in version 2.10.0.
