CVE-2026-86207

Estado: Pendiente de análisisAlta (7.7)—

An authentication bypass in N-central < 2026.3 HF 3 leads to authentication bypass in internal only APIs

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.

CWE-305 (autenticación insuficiente) en API interna con PR:L permite escalada; T1078 (obtención de acceso válido) es el impacto directo del bypass.

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.
