WP Video Lightbox < 1.9.7 is vulnerable to Authenticated (Contributor+) Stored Cross-Site Scripting (XSS) vulnerability

The WP Video Lightbox for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in versions up to, and including, 1.9.6 due to insufficient input sanitization and output escaping on supplied attributes. This makes it possible for authenticated attackers with contributor-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
