Name of the Vulnerable Software and Affected Versions WPBakery Page Builder for WordPress versions up to, and including, 8.4.1

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

Recommendations For versions up to, and including, 8.4.1, update to a version that addresses the insufficient input sanitization and output escaping issue in the Grid Builder feature. As a temporary workaround, consider restricting access to the Grid Builder feature to minimize the risk of exploitation.
