Name of the Vulnerable Software and Affected Versions Blocksy theme for WordPress versions up to, and including, 2.0.46

Description The issue is related to Stored Cross-Site Scripting via the has field link rel parameter 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, which will execute when a user accesses an injected page.

Recommendations For versions up to, and including, 2.0.46, update to a version higher than 2.0.46 to resolve the issue. As a temporary workaround, consider restricting access to the has field link rel parameter to minimize the risk of exploitation.
