CVE-2026-59782

Estado: Pendiente de análisisMedia (6.9)—

The JavaScript preprocessing (Duktape) engine on Zabbix server has a vulnerability where a limited administrator is able to read raw heap data potentially resulting in leaked data from other running preprocessors not available to said administrator.

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.

Acceso red con PR:H (admin limitado) en servicio remoto Zabbix; heap dump revela datos de otros procesos (T1005, T1552). No es T1059 pese a sugerencia.

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.
