Name of the Vulnerable Software and Affected Versions The Ultimate Blocks – WordPress Blocks Plugin versions up to, and including, 3.0.8

Description The issue is related to Stored Cross-Site Scripting via the plugin's tab anchor metabox 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, 3.0.8, update to a version higher than 3.0.8 to resolve the issue. As a temporary workaround, consider restricting access to the tab anchor metabox for users with contributor-level and above permissions to minimize the risk of exploitation.
