NGG Smart Image Search <= 3.3.3 is vulnerable to Cross Site Scripting (XSS) Vulnerability

The NGG Smart Image Search plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.3 due to insufficient 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.
