Cisco Warns of Active Exploitation of Critical ISE Flaw
Cisco warns that CVE-2026-76460 (CVSS 10.0) in Identity Services Engine is actively exploited, enabling unauthenticated root access; CISA added it to KEV.
Cisco disclosed CVE-2026-76460, a CVSS 10.0 flaw caused by insufficient control of an API endpoint in Cisco ISE and ISE-PIC, allowing crafted requests to bypass the web-based management interface and potentially obtain root command execution. Active exploitation is confirmed; patches are available and no workarounds exist, though infrastructure access control lists can restrict management traffic as an interim measure. CISA added the flaw to its Known Exploited Vulnerabilities catalog, requiring FCEB agencies to prioritize patching. Cisco urges checking access.log on every node, reimaging suspected compromised nodes, and reviewing external firewall logs for unexpected uploads.
