Description¶

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.
