CVE-2026-20300
Estado: Pendiente de análisisAlta (7.1)—
A vulnerability in Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected device. To exploit this vulnerability, the attacker must have at least low-privileged administrative credentials.
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 read or modify data in the underlying database.
