Cisco confirmed attackers are exploiting CVE-2026-76460, a CVSS 10.0 flaw giving unauthenticated root on Identity Services Engine. ISE decides which devices join the network, so a rooted node hands over every access decision and the device credentials it stores.
Reality
Cisco says CVE-2026-76460 is under active exploitation. It scores 10.0, needs no credentials, and puts an unauthenticated attacker past the web management interface of an Identity Services Engine appliance.

Cisco's PSIRT says CVE-2026-76460 is being exploited, and the company has published no workaround, so the fix is a branch-specific patch. ISE 3.0 is past End of Software Maintenance and gets a migration.
Reality
CVE-2026-76460 scores a CVSS 10.0, affects Cisco ISE and ISE-PIC in every configuration, and has no workaround. CISA added it to the KEV catalog the day the patches shipped and gave federal agencies three days.
