Visual Portfolio, Photo Gallery & Post Grid < 3.3.3 - Authenticated (Author+) Stored Cross-Site Scripting via title_tag Parameter

Description

The Visual Portfolio, Photo Gallery & Post Grid plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘title_tag’ parameter in all versions up to, and including, 3.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
