SP Blog Designer Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the SP Blog Designer plugin for WordPress, affecting all versions through 1.0.0. The issue arises in the 'design' attribute of the 'wpsbd_post_carousel' shortcode, where inadequate input sanitization and output escaping allow authenticated attackers with Contributor-level access or higher to inject arbitrary scripts. These scripts are executed when a user views the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
