Responsive Lightbox2 <= 1.0.3 is vulnerable to Auth. Stored Cross-Site Scripting (XSS) vulnerability

The Responsive Lightbox2 plugin for WordPress is vulnerable to Authenticated (Contributor+) Stored Cross-Site Scripting via the plugin's shortcode parameters (title, url, hyperlink) in the shortcode_handler function in versions up to, and including, 1.0.3 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
