No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The RomanCart Ecommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'blclass' attribute (and other attributes) of the romancart_button shortcode in versions up to, and including, 2.0.8. This is due to insufficient input sanitization and output escaping on user supplied attributes within the romancart_button_shortcode() function. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
