Elegant Themes Divi Theme, Extra Theme, Divi Page Builder <= 4.25.0 - Authenticated (Contributor+) DOM-Based Stored Cross-Site Scripting

Description

The Elegant Themes Divi theme, Extra theme, and Divi Page Builder plugin for WordPress are vulnerable to DOM-Based Stored Cross-Site Scripting via the ‘title’ parameter in versions up to, and including, 4.25.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
