Sandbox escape due to integer overflow in the Graphics: Canvas2D component. This vulnerability was fixed in Firefox 143.0.3.

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 apunta a T1190. El escape de sandbox (CWE-190: integer overflow) permite ejecución de código nativo fuera del navegador, logrado mediante explotación remota de Canvas2D en Firefox.

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.
