Cisco patched a critical, actively exploited authentication bypass vulnerability (CVE-2026-76460) in its Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) platforms that could grant remote attackers root-level command execution via a management API.

◆ ◆ The Wire takeaway
You need to prioritise updating any Cisco ISE or ISE-PIC deployments immediately to prevent attackers gaining root access through the management API. Restrict management interface access as a quick step to reduce risk while patching.
