WordPress Content Flipper <= 0.1 - Authenticated (Contributor+) Stored Cross-Site Scripting

The WordPress Content Flipper plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'bgcolor' shortcode attribute of the 'flipper_front' shortcode in all versions up to, and including, 0.1. This is 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.
