CVE-2026-56826 — Shopper: Missing function-level authorization on Settings tax/zone/shipping Livewire components allows a low-privileged user to delete commerce configuration

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.3% (30-day exploitation probability)+3
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Shopperlabs Shopper, Composer Shopper/framework).
  2. Apply the fixed version or the patch documented under Remediation.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
