Name of the Vulnerable Software and Affected Versions: The Grey Opaque theme for WordPress versions up to, and including, 2.0.1

Description: The issue is related to Stored Cross-Site Scripting via the url parameter within the theme's Download-Button shortcode due to insufficient input sanitization and output escaping. This allows 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.

Recommendations: For versions up to, and including, 2.0.1, consider disabling the Download-Button shortcode until a patch is available to prevent exploitation. Restrict access to the url parameter within the shortcode to minimize the risk of arbitrary web script injection.
