Brizy Page Builder Stored Cross-Site Scripting Vulnerability via SVG File Upload

A stored cross-site scripting vulnerability has been identified in the Brizy Page Builder plugin for WordPress, affecting all versions through 2.6.8. This vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Author-level access or higher to inject arbitrary scripts into pages. The injected scripts execute when a user accesses the SVG file, exploiting the REST API's handling of SVG uploads.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the affected page.

Remediation

Users can update to Brizy Page Builder version 2.6.9 or later to address this vulnerability.
