Cisco Warns of New Zero-Day ISE Auth Bypass (CVSS 10.0) Exploited in Active Attacksnew

Cisco warns CVE-2026-76460 (CVSS 10.0), an unauthenticated ISE auth bypass leading to root command execution, is under active exploitation and was added to CISA's KEV.

Cisco warned that CVE-2026-76460 (CVSS 10.0), an insufficient-authentication flaw in an Identity Services Engine (ISE) API endpoint, is being actively exploited by unauthenticated remote attackers and can yield root-privilege command execution on ISE and ISE-PIC regardless of configuration. Fixes shipped across ISE 3.1 through 3.5 patch branches; Cisco advised reviewing access.log for unexpected usernames (e.g., "dummyuser"), re-imaging affected nodes, and using iACLs, since no workarounds exist. CISA added the flaw to its KEV catalog on September 16, 2026, requiring FCEB agencies to patch by September 19. Cisco simultaneously issued 77 new CVEs, 41 affecting ISE and 28 affecting Secure Firewall products, days after confirming active exploitation of CVE-2026-76461 in Secure Email Gateway.

America’s cyber strategy overlooks the infrastructure that actually keeps the military moving

Op-ed argues US cyber strategy underweights Iranian threats to ports, rail, utilities and other commercial infrastructure sustaining military operations.

The author, a former Navy intelligence officer, argues that a prolonged Iran conflict means sustained Iranian cyber operations targeting many smaller systems like water utilities, manufacturers and transportation providers. He cites mapping of 130 documented techniques across five Iranian threat groups and warns destructive attacks such as wipers and ransomware could hit the defense industrial base. The piece urges defensive wargames now and flags the pause in CMMC implementation as particularly concerning.
