Short explanation

The CVE-2026-56826 security flaw in the Shopper headless e-commerce admin panel allows low-privileged users to delete commerce configurations due to a lack of server-side authorization checks on the Livewire endpoint.

Why does it matter?

This vulnerability allows authenticated low-privileged users to delete carrier options, shipping zones, tax zones, and tax rates, disrupting checkout shipping, payment-method mapping, and tax calculation.

What should be done?

  • Upgrade Shopper to version 2.9.2 or above
  • Follow vendor advisories
  • Review access controls and component permissions

Show the technical text from the sources

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.
