CVE-2026-56826: Auth Bypass (CVSS 5.4)

Description

Shopper is a Headless e-commerce Admin Panel. From 2.0.0 until 2.9.2, authenticated users who could reach the Settings pages with only access_setting could directly invoke destructive actions through the Livewire endpoint because packages/admin/src/Livewire/Components/Settings/Zones/ZoneShippingOptions.php, packages/admin/src/Livewire/Components/Settings/Zones/Detail.php, packages/admin/src/Livewire/Components/Settings/Taxes/Detail.php, and packages/admin/src/Livewire/Components/Settings/Taxes/TaxRates.php did not enforce server-side delete authorization. The actions could delete carrier options, shipping zones, tax zones, and tax rates, disrupting checkout shipping, payment-method mapping, and tax calculation. This issue is fixed in version 2.9.2.
