Official description

The Simple Shopping Cart WordPress plugin before 5.2.6 does not escape some of its settings field values before outputting them on an admin settings page, allowing high-privilege users such as administrators to perform Stored Cross-Site Scripting attacks, which is notably impactful on multisite installations where administrators do not have the unfiltered_html capability.
