CVE-2026-76448: Cisco Identity Services Engine SQL Injection Vulnerability
A vulnerability in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct an SQL or HQL injection attack on an affected device. This vulnerability is due to insufficient validation of user-supplied input to the affected APIs before it is used to build database queries. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to execute arbitrary SQL or HQL queries against the underlying database, which could allow the attacker to view or modify data that they are not authorized to access. To exploit this vulnerability, the attacker must have valid administrative credentials.

Event History
Frequently Asked Questions
Who is realistically exposed to exploitation?
Only affected Cisco ISE or Cisco ISE-PIC deployments reachable by an authenticated remote user with valid administrative credentials are exposed. The vulnerability is in affected APIs that use insufficiently validated user input when building database queries.
What does an attacker need to exploit this issue?
An attacker needs valid administrative credentials and network access to send a crafted request to an affected device. No user interaction is required.
What could a successful exploit allow?
A successful exploit can execute arbitrary SQL or HQL queries against the underlying database. This may allow viewing or modifying data that the attacker is not authorized to access.
