CVE-2026-93377

Estado: AnalizadaAlta (8.8)—

Type confusion in V8 in Google Chrome prior to 153.0.8010.52 allowed a remote attacker leveraging social engineering to execute arbitrary code inside the 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 AV:N/UI:R indica explotación remota con interacción del usuario (T1203). Type confusion en V8 permite ejecución arbitraria de código (T1059) dentro del sandbox Chrome vía página HTML maliciosa.

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.
