CVE-2026-56828

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 viewusers and accessdashboard can mutate permissions, create an administrator, or delete roles. In packages/admin/src/Livewire/Components/Settings/Team/Permissions.php, togglePermission and removePermission authorize viewusers rather than the stronger accesssetting 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 accesssetting on the attacker's own role, or delete permission definitions.
