CVE-2025-12879

Estado: AplazadaAlta (8.8)—

The User Generator and Importer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.2.2. This is due to missing nonce validation in the "Import Using CSV File" function. This makes it possible for unauthenticated attackers to elevate user privileges by creating arbitrary accounts with administrator privileges via a forged request, provided they can trick a site administrator into performing an action such as clicking on a link.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

CSRF con UI:R requiere interacción del administrador. Impacto principal es creación de cuentas administrativas (T1136); secundario, modificación de cuentas existentes (T1098).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
