Vulnerability Title
WP User Frontend 3.5.29 - 4.3.11 - Unauthenticated Privilege Escalation via Registration Role Encryption
Source: CVE Program / CVE List V5
Vulnerability Description
The User Frontend WordPress plugin before 4.3.12 does not prevent tampering with the role assigned by its registration form, allowing unauthenticated users to register with a higher privileged role, such as Editor.
This affects installations running a PHP build where the sodium extension is unavailable, and where a registration page has been configured. The administrator role cannot be obtained this way.
