What is CVE-2026-19914?

The Welcart e-Commerce plugin for WordPress suffers from a Stored Cross-Site Scripting vulnerability due to inadequate input sanitization and output escaping in the 'custom_order' parameter. This allows unauthenticated attackers to inject malicious web scripts through the guest checkout form. These scripts execute when an administrator accesses the order within the WordPress admin panel, posing a security risk to the site and its users.
