# SureCart WordPress plugin: anonymous REST API leaks private merchant catalog data

The SureCart WordPress plugin before 4.9.5 lets an anonymous visitor read a single upsell funnel through its REST API and include related objects that should be private. Those objects expose merchant-private fields such as pricing, commission, stock, SKU, tax details and unpublished products.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed SureCart version in the WordPress admin plugin list or with `wp plugin get surecart --field=version`
- unknown

## Fix

- Update the SureCart plugin to `4.9.5` or later
- unknown

## From the sources

The SureCart  WordPress plugin before 4.9.5 does not restrict which related objects an anonymous visitor may include when reading a single upsell funnel through its REST API, nor strip private fields from those objects, allowing unauthenticated users to read merchant-private catalog data such as pricing, commission, stock, SKU and tax internals, including unpublished products.
