What is CVE-2026-104119?

The Simple Shopping Cart plugin for WordPress versions prior to 5.2.6 is affected by a vulnerability that results from improper escaping of settings field values when outputting them on the admin settings page. This flaw enables high-privilege users, such as administrators, to execute Stored Cross-Site Scripting (XSS) attacks. The impact is particularly significant in multisite environments, where certain administrators may lack the capability to use unfiltered HTML, heightening the risk of exploitation.
