The Brizy – Page Builder plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting in all versions up to, and including, 2.8.11 This is due to a combination of missing nonce verification for unauthenticated form submissions, insufficient handling of FileUpload fields when no file is uploaded, and the reversal of security encoding via html_entity_decode() followed by unescaped output in the admin view. The submit_form() function skips nonce verification for non-logged-in users (api.php:198). The handleFileTypeFields() function fails to overwrite user-supplied values when no file is attached. While htmlentities() is applied during storage, html_entity_decode() reverses this on display (form-entries.php:79). The form-data.php template outputs FileUpload values directly in href attributes without esc_url(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the form Leads page.
