FKIE_CVE-2026-4314

Vulnerability from fkie_nvd - Published: 2026-03-22 04:16 - Updated: 2026-04-24 16:32
Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
The 'The Ultimate WordPress Toolkit – WP Extended' plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.2.4. This is due to the `isDashboardOrProfileRequest()` method in the Menu Editor module using an insecure `strpos()` check against `$_SERVER['REQUEST_URI']` to determine if a request targets the dashboard or profile page. The `grantVirtualCaps()` method, which is hooked into the `user_has_cap` filter, grants elevated capabilities including `manage_options` when this check returns true. This makes it possible for authenticated attackers, with Subscriber-level access and above, to gain administrative capabilities by appending a crafted query parameter to any admin URL, allowing them to update arbitrary WordPress options and ultimately create new Administrator accounts.

Esto se debe a que el m\u00e9todo `isDashboardOrProfileRequest()` en el m\u00f3dulo Editor de Men\u00fa utiliza una comprobaci\u00f3n `strpos()` insegura contra `$_SERVER[\u0027REQUEST_URI\u0027]` para determinar si una solicitud apunta al panel de control o a la p\u00e1gina de perfil. El m\u00e9todo `grantVirtualCaps()`, que est\u00e1 enganchado al filtro `user_has_cap`, otorga capacidades elevadas, incluyendo `manage_options`, cuando esta comprobaci\u00f3n devuelve verdadero. Esto hace posible que atacantes autenticados, con acceso de nivel Suscriptor y superior, obtengan capacidades administrativas al a\u00f1adir un par\u00e1metro de consulta manipulado a cualquier URL de administraci\u00f3n, permiti\u00e9ndoles actualizar opciones arbitrarias de WordPress y, en \u00faltima instancia, crear nuevas cuentas de Administrador."
