CVE-2026-16392

Estado: AnalizadaCrítica (9.1)—

JIT miscompilation in the JavaScript Engine: JIT component. This vulnerability was fixed in Firefox 153 and Thunderbird 153.

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 indica acceso remoto sin privilegios ni interacción (AV:N, PR:N, UI:N). JIT miscompilation en motor JavaScript permite ejecución de código arbitrario remoto en navegador (T1190). Impactos: ejecución de comandos (T1059) y potencial corrupción de datos en memoria (I:H).

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.
