CVE-2026-76425 is a SQL injection vulnerability in Cisco Identity Services Engine (ISE) APIs. The issue stems from improper validation of certain parameters that are directly concatenated into SQL queries. An attacker with valid administrative credentials can send crafted requests to affected API endpoints to inject SQL commands. Successful exploitation can lead to unauthorized reading of database content and SSRF attacks. The vulnerability has a CVSS 3.1 base score of 7.6, indicating high severity, with attack vector network, low attack complexity, high privileges required, no user interaction, and impacts on confidentiality and integrity.

An attacker with valid administrative credentials can exploit this vulnerability to read arbitrary data from the backend SQL database and perform SSRF attacks. This compromises confidentiality and integrity of the system data but does not affect availability. The high privileges required limit the attack surface to authenticated administrators.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrative access to trusted users only and monitor for suspicious API activity. No official fix or patch links are provided in the current data.
