CVE-2026-56828
What it is
Shopper is a Headless e-commerce Admin Panel. From 2.8.0 until 2.8.1, three Shopper Livewire admin components retain authorization gaps after the earlier team-settings authorization fix. A staff member with only `view_users` and `access_dashboard` can mutate permissions, create an administrator, or delete roles. In `packages/admin/src/Livewire/Components/Settings/Team/Permissions.php`, `togglePermission` and `removePermission` authorize `view_users` rather than the stronger `access_setting` permission; `packages/admin/resources/views/livewire/components/settings/team/permissions.blade.php` exposes permission IDs in `wire:click` handlers. The attacker can grant arbitrary permissions to the bound role, including `access_setting` on the attacker's own role, or delete permission definitions. In `packages/admin/src/Livewire/SlideOvers/CreateTeamMember.php`, `mount()` and `store()` also accept `view_users`, and the client-selected `role_id` can identify the admin role, allowing creation of a pre-verified administrator with an attacker-chosen password. In `packages/admin/src/Livewire/Pages/Settings/Team/RolePermission.php`, `deleteAction` has no action authorization and is only conditioned on `can_be_removed`, while page access requires `view_users`. Deleting a removable role removes access for assigned users, enabling RBAC denial of service as well as privilege escalation. This issue is fixed in version 2.8.1.
