Detailsinfo

A vulnerability was found in Shopper Labs Shopper up to 2.7.x. It has been declared as critical. Affected by this vulnerability is the function Customers/Create::store/DNS1DFacade::getBarcodeHTML of the component Livewire Components. The manipulation of the argument password/barcode with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Shopper is a Headless e-commerce Admin Panel. Prior to 2.8.0, three related defects on admin Livewire components allowed data tampering, sensitive data disclosure, and stored XSS. First, several Livewire components in the admin panel exposed Eloquent model identifiers as public properties without the `#[Locked]` attribute. An authenticated user could rewrite the wire payload from the browser to target any record id, bypassing the implicit scoping enforced by the page routing. Second, `Customers/Create::store()` re-passed a `Hidden` `_password` form field straight into the create payload. The plaintext password was rendered into the HTML and transported through the Livewire snapshot in clear text, exposing credentials in the page DOM and in any logging that captures Livewire payloads. Finally, the product barcode field was rendered through `DNS1DFacade::getBarcodeHTML()` with `{!! !!}`. An attacker with `edit_products` permission could persist malicious payload in the barcode field that would execute in the browser of any admin user viewing that product, enabling session theft and privileged-action chaining. Starting in v2.8.0, all vulnerable Livewire model identifiers are now marked `#[Locked]`; `Customers/Create` no longer round-trips the password through a Hidden form field; the plaintext password is hashed at action boundary and never returned to the client; and the product barcode rendering now escapes the value before passing it to the barcode generator and the output is wrapped in an `<svg>` context that does not interpret event handlers. No known workarounds are available.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-47743 since 05/20/2026. The exploitation appears to be easy. The attack can be launched remotely. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.

Upgrading to version 2.8.0 eliminates this vulnerability.
