CVE-2026-76448 Cisco CVE debrief

Who should care

Cisco ISE and ISE-PIC administrators, security teams responsible for identity services and network access control, and operators of affected systems should assess exposure, verify patches, and monitor database activity to prevent potential data exposure and unauthorized access.

Why it matters

CVE-2026-76448 is a medium-severity SQL injection vulnerability in Cisco ISE and ISE-PIC that allows authenticated remote attackers to execute arbitrary SQL or HQL queries. Cisco ISE and ISE-PIC administrators should assess exposure, verify patches, and monitor database activity.

• Potential data exposure through unauthorized database queries
• Risk of elevated privileges for attackers with administrative credentials
• Need for verification of patch deployment and monitoring of database activity
• Possible lateral movement within the network

Technical summary

CVE-2026-76448 is a SQL injection vulnerability in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC). Insufficient input validation allows authenticated remote attackers to execute arbitrary SQL or HQL queries. Cisco provides advisory details. The 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.

Defensive priority

Medium priority for Cisco ISE and ISE-PIC administrators to assess exposure and verify patches

Recommended defensive actions

• Assess exposure of Cisco ISE and ISE-PIC deployments
• Verify administrative credential security
• Review database query logging and monitoring
• Apply patches when available
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
