Slideshow SE <= 2.5.5 is vulnerable to Auth. Cross-Site Scripting (XSS) vulnerability

The Slideshow SE plugin for WordPress is vulnerable to Stored Cross-Site Scripting in certain plugin configurations in versions up to, and including, 2.5.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
