Name of the Vulnerable Software and Affected Versions Blocksy theme for WordPress versions up to, and including, 2.0.39

This allows authenticated attackers with contributor access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For Blocksy theme for WordPress versions up to, and including, 2.0.39, consider updating to a version that addresses the insufficient input sanitization and output escaping issue.
