CVE-2026-7337

Estado: AnalizadaAlta (8.8)—

Type Confusion in V8 in Google Chrome prior to 147.0.7727.138 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

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.

Vector CVSS con UI:R (requiere interacción del usuario) indica ejecución en cliente T1203. Type Confusion en V8 permite ejecución arbitraria de código JavaScript dentro del navegador Chrome tras abrir una página HTML preparada.

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.
