CVE-2025-69234

Estado: AnalizadaCrítica (9.1)—

Whale browser before 4.35.351.12 allows an attacker to escape the iframe sandbox in a sidebar environment.

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.

Escape de sandbox en iframe de sidebar permite ejecutar código arbitrario (C:H, I:H) en navegador remoto sin privilegios; acceso red sin autenticación (AV:N/PR:N/UI:N) tipifica explotación de aplicación expuesta. CWE-358 (observabilidad incorrecta) refuerza bypassing de restricciones de seguridad.

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.
