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

The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'bt_bb_shortcode' shortcode in all versions up to, and including, 5.6.8 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
