How to Fix CVE-2026-47743

To remediate this vulnerability, upgrade all affected Shopper dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

shopper/framework fixed: 2.8.0 
Upgrade shopper/framework to 2.8.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for shopper/framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-47743, inspect your project dependencies for Shopper:

inspect dependencies for shopper/framework

Analyze the terminal output to locate any version of Shopper in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.8.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. In Shopper, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Impact Three related defects on admin Livewire components allowed data tampering, sensitive data disclosure, and stored XSS: - **IDOR via unlocked properties.** 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. - **Sensitive data echoed back through Hidden form field.** `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. - **Stored XSS on product barcode.** 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. ## Patches Fixed 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. - 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. Upgrade via: ```bash composer require shopper/admin:^2.8 ``` ## Workarounds None. Upgrade to `v2.8.0`.
