Vulnerability from fkie_nvd - Published: 2026-03-03 05:17 - Updated: 2026-04-22 21:26
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 User Registration & Membership – Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to improper privilege management in all versions up to, and including, 5.1.2. This is due to the plugin accepting a user-supplied role during membership registration without properly enforcing a server-side allowlist. This makes it possible for unauthenticated attackers to create administrator accounts by supplying a role value during membership registration.

Esto se debe a que el plugin acepta un rol proporcionado por el usuario durante el registro de membres\u00eda sin aplicar correctamente una lista de permitidos del lado del servidor. Esto hace posible que atacantes no autenticados creen cuentas de administrador al proporcionar un valor de rol durante el registro de membres\u00eda."
