Description

The WP YouTube Video Optimizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ib_youtube' shortcode in all versions up to, and including, 1.2 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.
