Brizy – Page Builder <= 2.4.43 - Authenticated (Contributor+) Stored Cross-Site Scripting via Custom Attributes

Vulnerability Description

The Brizy – Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Custom Attributes for blocks in all versions up to, and including, 2.4.43 due to insufficient input sanitization and output escaping. This makes it possible for 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.
