CVE-2026-76428Network attack vector

Session database disclosure via unparameterized SQL clauses

Published Sep 16, 2026 · Updated Sep 18, 2026

SQL injection in Cisco ISE and ISE-PIC affected releases allows remote authenticated users to read information from the session database. The REST APIs concatenate attacker-controlled parameter values directly into SQL clauses instead of using parameterized queries. Exploitation requires valid administrative credentials, and the affected products are exposed regardless of device configuration.
