What is CVE-2026-5523?

The Divi Form Builder plugin for WordPress has a vulnerability that permits unauthorized users with subscriber-level access or higher to manipulate user accounts. This occurs because the update_user() function does not validate the authenticated user's permissions when handling user ID parameters from form submissions. Additionally, the handle_register_submission() function only verifies that a user is logged in, failing to check permissions for the user account being updated. As a result, attackers can change email addresses and passwords, potentially leading to complete account takeover for any user, including administrators.

Affected Version(s)

Divi Form Builder 0 <= 5.1.8
