CVE-2026-76460 is an insufficient-authentication-control vulnerability in an API endpoint of Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC). The affected endpoint does not correctly enforce authentication before performing privileged access operations. An unauthenticated remote attacker can submit a crafted request to the endpoint to bypass web-based management-interface authentication and obtain unauthorized access to the appliance.
