CVE-2026-56828 · Severity: high · CVSS 8.8 · Published 2026-10-28

Shopper is an e-commerce admin framework built on Laravel/Livewire. A support staff member with read-only "view_users" permission can exploit three unpatched admin components to escalate their privileges: grant themselves any admin permission, create a new admin account with full privileges, or delete entire user roles. This allows complete takeover of the shop's administrative backend without admin credentials.

## Technical details

The vulnerability stems from inconsistent authorization checks across three Livewire components (Permissions.php, CreateTeamMember.php, RolePermission.php). These components gate state-mutating actions on the read-only "view_users" permission instead of the write-level "access_setting" permission. Specifically: (1) Permissions::togglePermission and removePermission allow any view_users user to modify role permissions; (2) CreateTeamMember::store creates new admin accounts with attacker-chosen credentials without checking access_setting; (3) RolePermission::deleteAction lacks any authorization chain, permitting role deletion for users with only view_users. The components enumerate permission IDs directly in UI handlers, requiring no brute-force. The vulnerability is a residual gap from a prior partial fix (GHSA-f946-9qp6-vgch) and even appears in new code introduced by that patch. Requires valid staff login but no additional interaction.
