Name of the Vulnerable Software and Affected Versions Blocksy Companion plugin for WordPress versions up to, and including, 2.0.31

Description The issue is related to Stored Cross-Site Scripting via the plugin's Newsletter widget due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.0.31, update to a version higher than 2.0.31 to resolve the issue. As a temporary workaround, consider restricting access to the Newsletter widget for users with contributor-level and above permissions until a patch is available.
