CVE-2026-20247

Estado: Pendiente de análisisAlta (7.5)—

A vulnerability in Cisco ISE could allow an unauthenticated, remote attacker to conduct SQL injection attacks on an affected device.

This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to modify data in the underlying database.

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).
