VI: Include Post By <= 0.4.200706 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'class_container' Shortcode Attribute
Description
The VI: Include Post By plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'class_container' attribute of the 'include-post-by-cat' shortcode in all versions up to, and including, 0.4.200706 due to insufficient input sanitization and output escaping on user supplied attributes.
