FKIE_CVE-2026-3629

Vulnerability from fkie_nvd - Published: 2026-03-21 23:16 - Updated: 2026-04-24 16:31
Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
The Import and export users and customers plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.29.7. This is due to the 'save_extra_user_profile_fields' function not properly restricting which user meta keys can be updated via profile fields. The 'get_restricted_fields' method does not include sensitive meta keys such as 'wp_capabilities'. This makes it possible for unauthenticated attackers to escalate their privileges to Administrator by submitting a crafted registration request that sets the 'wp_capabilities' meta key. The vulnerability can only be exploited if the "Show fields in profile" setting is enabled and a CSV with a wp_capabilities column header has been previously imported.

      "value": "El plugin Importar y exportar usuarios y clientes para WordPress es vulnerable a escalada de privilegios en todas las versiones hasta, e incluyendo, la 1.29.7. Esto se debe a que la funci\u00f3n \u0027save_extra_user_profile_fields\u0027 no restringe adecuadamente qu\u00e9 claves meta de usuario pueden ser actualizadas a trav\u00e9s de los campos de perfil. El m\u00e9todo \u0027get_restricted_fields\u0027 no incluye claves meta sensibles como \u0027wp_capabilities\u0027. Esto hace posible que atacantes no autenticados escalen sus privilegios a Administrador al enviar una solicitud de registro manipulada que establece la clave meta \u0027wp_capabilities\u0027. La vulnerabilidad solo puede ser explotada si la configuraci\u00f3n \"Mostrar campos en el perfil\" est\u00e1 habilitada y se ha importado previamente un CSV con un encabezado de columna wp_capabilities."
