What is CVE-2026-56830?
CVE-2026-56830 is a medium-severity missing authorization vulnerability in shopperlabs shopper, published on 15 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Shopper is a Headless e-commerce Admin Panel. Prior to 2.9.2, an earlier product sub-form hardening change left store() in packages/admin/src/Livewire/Components/Products/Form/Media.php without the edit_products authorization check used by sibling sub-forms. An authenticated staff user with browse_products can invoke the Livewire store action and replace the thumbnail and gallery images for a product whose Media component was initialized, even without product-edit permission. The product binding is locked, so the attacker cannot redirect the update to an arbitrary product through client-side ID substitution, and the impact is limited to products whose edit pages were loaded. This issue is fixed in version 2.9.2.
Weakness: CWE-862
