Technical details

A missing $this->authorize('edit_products') call in the Media.php store() method (lines 64–76) allows privilege escalation via Livewire RPC. The vulnerable component accepts authenticated requests from staff holding browse_products permission and updates product media fields via $this->product->update($this->form->getState()) without verifying edit_products capability. Although the $product property is server-side locked (preventing arbitrary product targeting), the permission gate is entirely absent. An attacker must be an authenticated admin-panel user and must have previously loaded the target product's edit page in their session (to capture the Livewire snapshot), but the exploit itself is trivial: a single POST to /shopper/livewire/update with the stored snapshot and a call to store(). This is a regression from an incomplete prior patch (GHSA-h4mp-g9c6-xwph) that fixed five sibling sub-form components but omitted Media from the remediation list.
