CVE-2026-86860

Estado: Pendiente de análisisCrítica (9.3)—

ServiceNow has remediated a missing authorization vulnerability that was identified in the ServiceNow AI Platform. This vulnerability could enable an unauthenticated user, in certain circumstances, to extract instance data beyond what was intended, resulting in privilege escalation.

ServiceNow deployed a security update to hosted instances and ServiceNow provided the update to our partners and self-hosted customers. We are not currently aware of malicious exploitation against ServiceNow instances. We recommend customers promptly apply appropriate updates or upgrade to a patched release if they have not already done so.

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.

Vulnerabilidad de autorización faltante (CWE-862) en aplicación web expuesta (AV:N, PR:N) permite a usuario no autenticado extraer datos y escalar privilegios; acceso a credenciales/cuentas y exfiltración de datos de instancia.

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.
