Cisco drops another exploited zero-day, this time a perfect 10new

Cisco's CVSS 10.0 CVE-2026-76460 authentication bypass in Identity Services Engine is actively exploited, granting unauthenticated attackers root command execution.

Cisco disclosed CVE-2026-76460 (CVSS 10.0), an authentication bypass in Identity Services Engine (ISE) and ISE-PIC APIs that gives unauthenticated remote attackers command execution with root privileges; CISA added it to the KEV catalog. It follows CVE-2026-76461 (CVSS 9.8), an actively exploited flaw in Cisco Secure Email Gateway and Secure Email and Web Manager disclosed days earlier. Permanent fixes ship in ISE 3.1 Patch 12 through 3.5 Patch 4; ISE 3.0 is end-of-maintenance and ISE 3.1 Patch 12, 3.2 Patch 11, 3.3 Patch 12, 3.4 Patch 7 and 3.5 Patch 4 are available. No workaround exists, though ACLs restricting management traffic can serve as temporary mitigation.

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.

12 Serverless Security Options Compared (2026): Features & Pricing

A buyer-focused comparison of twelve serverless security offerings concludes no standalone SKU is worth buying in 2026, with function protection bundled inside CNAPP contracts.

The scorecard compares twelve serverless security options on function-protection depth, pricing visibility, platform attach economics, multi-runtime coverage, and vendor viability. Microsoft Defender for Cloud tops the weighted scores at 4.75, with Prisma Cloud at 4.60 and Datadog at 4.55 noted for publishing clean per-function rates. The piece warns that Thundra and Epsagon are defunct and that most vendors bill functions inside platform units where costs are hard to see. It also references the Aqua Security Trivy supply chain incident and Google's finalized acquisition of Wiz as market context.
