CVE-2026-56827: Missing authorization vulnerability

Shopper is a Headless e-commerce Admin Panel. Prior to 2.9.2, groupedBulkActions in packages/admin/src/Livewire/Pages/Attribute/Browse.php, packages/admin/src/Livewire/Pages/Tag/Index.php, packages/admin/src/Livewire/Pages/Brand/Index.php, packages/admin/src/Livewire/Pages/Category/Index.php, and packages/admin/src/Livewire/Pages/Supplier/Index.php omit server-side authorization while the pages require only browse_attributes, browse_tags, browse_brands, browse_categories, or browse_suppliers. A browse-only staff user can invoke DeleteBulkAction to mass delete attributes or tags and can invoke BulkAction::make('enabled') or BulkAction::make('disabled') to change attribute, brand, category, or supplier visibility. These operations can break product variants and substantially disrupt storefront catalog visibility. Per-record actions and the comparison pages identified by the advisory are correctly authorized and are not affected. This issue is fixed in version 2.9.2.
