The Divi Form Builder plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 5.1.8. This is due to the updateuser() function accepting a user ID parameter from form submissions without verifying that the authenticated user has permission to edit that specific user account, and the handleregistersubmission() function only checking if any user is logged in rather than validating permissions for the target user. This makes it possible for authenticated attackers, with subscriber-level access and above, to change the email address and password of any user account, including administrators, resulting in complete account takeover.
The Divi Torque Lite – Best Divi Addon, Extensions, Modules & Social Modules plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several widgets in all versions up to, and including, 4.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Divi theme for WordPress is vulnerable to Stored Cross-Site Scripting via the redirecturl parameter of the etpbcontactform shortcode in all versions up to, and including, 4.27.6. This is due to the redirecturl attribute being sanitized with escattr() instead of escurl() before being rendered into the data-redirecturl HTML data attribute. Additionally, redirecturl is absent from the hardcoded $urloptions array in class-et-builder-element.php, so it does not receive escurlraw() sanitization during shortcode parsing. After a successful form submission, client-side JavaScript reads this data attribute and passes it directly to window.location.href, executing arbitrary JavaScript from a javascript: URI. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that execute whenever a user submits the contact form.
