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. 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.
