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.","state":0,"publishedAt":"2026-10-28T15:40:39.294+00:00","modifiedAt":"2026-10-28T15:40:39.294+00:00","affected":[{"ecosystem":"Vendor product","name":"shopper","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"shopperlabs\",\n                    \"product\": \"shopper\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.8.0, < 2.8.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/shopperlabs/shopper/security/advisories/GHSA-j328-xmgp-j4q3","https://github.com/shopperlabs/shopper/pull/514","https://github.com/shopperlabs/shopper/commit/ac9a76044a8e4a2b570b438d66cf3007f3dc479e","https://github.com/shopperlabs/shopper/compare/v2.8.1...v2.9.2","https://github.com/shopperlabs/shopper/releases/tag/v2.8.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56828","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56828","identifiers":["CVE-2026-56828"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
