# SureCart WordPress plugin: stored XSS through input handling up to 4.9.5

SureCart, a WordPress e-commerce plugin by Brainstorm Force, fails to neutralize some user input before it is rendered in pages, enabling stored cross-site scripting. An attacker who can store content in the plugin can run scripts in other visitors' browsers, including administrators.

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

## How to check

- Check the installed SureCart plugin version in the WordPress admin Plugins screen or with `wp plugin get surecart --field=version`
- Compare the result against the fixed version `4.9.5` and confirm whether any version at or below it is installed

## Fix

- Update the SureCart plugin to a version later than `4.9.5` as published by the vendor (fixed version unknown from sources)
- Until updated, restrict which accounts can submit or edit stored content in SureCart forms
