Vulnerability Overview

The BootStrap Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'class' and 'id' parameters in the 'bs_dropdown' shortcode in versions up to, and including, 3.4.0. This makes it possible for authenticated attackers with the 'edit posts' capability, such as contributors, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
