How to Fix CVE-2026-47742

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-2026-47742, 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. 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 Sub-form Livewire components used in the product editor (`Edit`, `Inventory`, `Seo`, `Shipping`, `Files`) had no authorization on their `store()` method. Any authenticated panel user, regardless of role, could mutate any product's pricing, stock, SEO metadata, shipping dimensions, and attached media without holding `edit_products`. The affected components accepted the product ID as a public Livewire property without `#[Locked]`, so an attacker could also target an arbitrary product by tampering with the wire payload from the client. ## Patches Fixed in `v2.8.0`. Each sub-form `store()` now authorizes against `edit_products` and the product binding is locked. Upgrade via: ```bash composer require shopper/admin:^2.8 ``` ## Workarounds None. Upgrade to `v2.8.0`. ## References - Pull request: https://github.com/shopperlabs/shopper/pull/511 - CWE-862 Missing Authorization
