CVE-2026-92144

Estado: AplazadaAlta (7.2)—

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'postdata-1[post-custom]' Parameter in all versions up to, and including, 1.57.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The required form submission nonce is freely obtainable by unauthenticated users via the publicly accessible wp_ajax_nopriv_forminator_get_nonce endpoint, making the full attack chain exploitable without any authentication or prior account.

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.

AV:N sin autenticación en aplicación web (WordPress plugin) expuesta públicamente. XSS almacenado (CWE-79) permite inyección de scripts arbitrarios ejecutables en navegadores de usuarios; nonce público facilita cadena completa sin autenticación.

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.
