Use after free in Cast in Google Chrome prior to 153.0.8010.36 allowed an adjacent attacker to potentially execute arbitrary code outside the sandbox via crafted network traffic. (Chromium security severity: Critical)

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:A (red adyacente) + use-after-free (RCE fuera del sandbox) → T1210. Impactos: ejecución arbitraria de código (T1059) y escalada de privilegios al escapar sandbox (T1068).

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.
