FKIE_CVE-2026-5118

Vulnerability from fkie_nvd - Published: 2026-05-21 13:16 - Updated: 2026-07-23 16:10
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
The Divi Form Builder plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.1.2. This is due to the plugin accepting a user-controlled 'role' parameter from POST data during user registration without validating it against the form's configured default_user_role setting. This makes it possible for unauthenticated attackers to create administrator accounts by tampering with the role parameter during registration.
