Codeless Page Builder <= 1.1.4 - Contributor+ Stored XSS via Shortcode Attribute

The Codeless Page Builder WordPress plugin through 1.1.4 does not sanitize or validate a shortcode attribute before using it as an HTML tag name when rendering content, allowing users with contributor-level access and above to inject arbitrary HTML and JavaScript that executes in the session of any higher-privileged user (such as an administrator) who views the content.
