CVE-2026-104119: Unknown Simple Shopping Cart

Low severity, CVSS 3.5. EPSS: 0.1% chance of exploitation in the next 30 days.

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.
