description

Simple Shopping Cart versions earlier than 5.2.6 can render stored settings values as active browser content on an administrative settings page. A high-privilege authenticated user can trigger script execution for users viewing that page; multisite deployments with restricted administrator HTML privileges are particularly affected.

mitigation

Upgrade Simple Shopping Cart to version 5.2.6 or later. Until upgraded, restrict access to the plugin's settings controls to trusted administrators.

fixed in 5.2.6
