Description

The Basil recipe theme for WordPress is vulnerable to Persistent Cross-Site Scripting (XSS) via the `post_title` parameter in versions up to, and including, 2.0.4 due to insufficient input sanitization and output escaping.

Because the of the default WordPress validation, it is not possible to insert the payload directly but if the Cooked plugin is installed, it is possible to create a recipe post type (cp_recipe) and inject the payload in the title field. Version 2.0.5 contains a patch for the issue.
