CVE-2026-62991

Shopper, a Headless e-commerce Admin Panel prior to 2.8.0, contains two authorization defects in team settings. These allow any authenticated user to take over the RBAC system, create new roles, delete other users (including administrators), and escalate privileges to full panel administrator.

A stored XSS vulnerability in the Shopper admin panel allows an authenticated staff member with content-upload permissions to store executable HTML or SVG files that are served without Content-Disposition or CSP headers. When an administrator opens such a file, the malicious script executes in their session and can create a new attacker-controlled administrator account with a chosen password. The issue affects versions 2.0.0 through 2.10.0 and 3.0.0-beta.1/beta.2, and is fixed in 2.10.1 and 3.0.0-beta.3.

In Shopper before 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 obtain the signed component state and permanently delete individual or multiple variants without the delete_product_variants permission. This can destroy the sellable catalogue and disrupt storefront product pages, cart, and checkout. The issue is fixed in version 2.10.0.

Shopper is a headless e-commerce admin panel. From 2.8.0 until 2.8.1, three Livewire admin components retain authorization gaps: a staff member with only `view_users` and `access_dashboard` can mutate permissions, create an administrator, or delete roles. They can grant arbitrary permissions including `access_setting` to their own role, create a pre-verified administrator with a chosen password, or delete roles, enabling privilege escalation and RBAC denial of service.

Shopper from 2.0.0 before 2.6.0 contains a missing authorization vulnerability that allows admin-panel users with only `access_dashboard` to create administrators and grant permissions. Attackers can call `CreateTeamMember::store()` or `Permissions::togglePermission()` directly over `/livewire/update` to create admin accounts and escalate to full administrator.

In the Shopper Headless e-commerce Admin Panel, from version 2.0.0 until 2.9.2, authenticated users with only access_setting could invoke destructive actions through the Livewire endpoint because the settings components for shipping zones, tax zones, and tax rates did not enforce server-side delete authorization. This allowed deletion of carrier options, shipping zones, tax zones, and tax rates. The issue is fixed in version 2.9.2.

Shopper is a Headless e-commerce Admin Panel. Prior to 2.9.0, the /cpanel/discounts administrative interface accepts negative fixed_amount discount values, persists them in sh_discounts, and passes them through DiscountCalculator.php and Calculate.php without enforcing a positive-value invariant. Because the calculation subtracts discountTotal from the subtotal, a negative discount increases the resulting order total instead of reducing it.

Shopper is a Headless e-commerce Admin Panel. Prior to 2.9.2, an earlier product sub-form hardening change left store() in Media.php without the edit_products authorization check used by sibling sub-forms. An authenticated staff user with browse_products can invoke the Livewire store action and replace the thumbnail and gallery images for a product whose Media component was initialized, even without product-edit permission.

In Shopper before 2.9.2, packages/admin/src/Livewire/Components/Products/VariantStock.php exposes stockAction() without edit_product_variants authorization and leaves public $variant client mutable because it lacks the Livewire Locked attribute. Any authenticated admin-panel user, including staff with only browse_products, can select an arbitrary product variant and inventory location through component state, then submit a positive or negative quantity adjustment. This permits browse-only staff to inflate stock, reduce stock, or force out-of-stock states for variants outside the current page. Fixed in version 2.9.2.

In Shopper before 2.9.2, groupedBulkActions in packages/admin/src/Livewire/Pages/Attribute/Browse.php, Tag/Index.php, Brand/Index.php, Category/Index.php, and 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. Fixed in version 2.9.2.
