{"id":"CVE-2026-56828","state":"PUBLISHED","title":"Shopper: read-only team permissions allow administrator creation and permission escalation","description":"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.","publishedAt":"2026-10-28T15:40:39.294Z","updatedAt":"2026-10-28T15:40:39.294Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["shopperlabs shopper"],"affected":[{"vendor":"shopperlabs","product":"shopper","versions":[{"version":">= 2.8.0, < 2.8.1","status":"affected"}]}],"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"],"weaknesses":["CWE-285","CWE-862"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/56xxx/CVE-2026-56828.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-56828","state":"PUBLISHED","datePublished":"2026-10-28T15:40:39.294Z","dateUpdated":"2026-10-28T15:40:39.294Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-23T14:55:09.117Z"},"containers":{"cna":{"title":"Shopper: read-only team permissions allow administrator creation and permission escalation","descriptions":[{"lang":"en","value":"Shopper is a Headless e-commerce Admin Panel.
