DescriptionNVD

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.

AnalysisAI

Privilege escalation in the Divi Form Builder WordPress plugin (versions ≤5.1.2) allows unauthenticated remote attackers to register administrator accounts by submitting a tampered 'role' parameter in the registration POST body. The plugin trusts the client-supplied role value instead of enforcing the form's configured default_user_role, yielding full WordPress site takeover. …

WITHIN 7 DAYS: If plugin functionality is required, restrict registration form access to authenticated users only; deploy WAF rules blocking POST requests with suspicious role parameters; enable logging and alerting on new administrator account creation. …
