CVE-2026-5324
HighSummary
The Brizy – Page Builder plugin for WordPress is vulnerable to unauthenticated stored Cross-Site Scripting (XSS) in versions up to 2.8.11. The issue arises from missing nonce verification for unauthenticated form submissions and insufficient handling of FileUpload fields, allowing attackers to inject malicious scripts.
Risk Assessment
Attackers can inject malicious scripts that execute when an administrator views the form Leads page, potentially leading to data theft or account takeover.
Recommendation
It is recommended to update the plugin to the latest version and implement additional nonce verification mechanisms for forms. Also, improve the handling of FileUpload fields and secure data output.

Original NVD description (English source)
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.
