CVE-2026-5523: Divi Form Builder <= 5.1.8 - Authenticated (Subscriber+) Missing Authorization to Privilege Escalation via User Profile Update Form

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-639

Description

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 update_user() 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 handle_register_submission() 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.

Affected products

• Divi Engine Divi Form Builder: through 5.1.8
