Description

The Shortcodes Bootstrap plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'type' parameter in the [notification] shortcode in all versions up to, and including, 1.1. This is due to missing input sanitization and output escaping. 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.
