CVE-2026-59569

Estado: Pendiente de análisisAlta (8.1)—

An improper input validation vulnerability in Zscaler Client Connector on Android and ChromeOS allows an attacker to potentially bypass Zscaler controls.

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:L + PR:H sin interacción → escalada de privilegios (T1068). La vulnerabilidad de validación en controles de seguridad Zscaler permite bypass (impersonación/manipulación de políticas T1556) y potencial SSRF/proxy (T1090) al eludir restricciones de red.

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.
