Name of the Vulnerable Software and Affected Versions Blocksy theme for WordPress versions up to, and including, 2.0.42

Description The issue is related to Stored Cross-Site Scripting via the tagName parameter due to insufficient input sanitization and output escaping. This allows authenticated attackers with contributor-level permissions 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, 2.0.42, update to a version higher than 2.0.42 to resolve the issue. As a temporary workaround, consider restricting access to the tagName parameter to minimize the risk of exploitation.
