title: Beaver Builder – WordPress Page Builder <= 2.5.5.2 - Authenticated Stored Cross-Site Scripting via Image URL
description: The Beaver Builder – WordPress Page Builder for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Image URL' value found in the Media block in versions up to, and including, 2.5.5.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with access to the Beaver Builder editor to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
