Emerging Threat: Cisco Catalyst SD-WAN Authentication Bypass (CVE-2026-20127)

CVE-2026-20127 is a critical authentication bypass vulnerability affecting Cisco Catalyst SD-WAN Controller (vSmart) and Cisco Catalyst SD-WAN Manager (vManage). The flaw stems from improper validation within the control plane and management plane authentication mechanisms, allowing a remote, unauthenticated attacker to submit crafted requests that bypass standard authentication controls. Successful exploitation results in access to the system as a high-privileged internal user account.

CVE-2026-20127: Cisco Catalyst SD-WAN Controller Authentication Bypass Vulnerability

On February 25, 2026, Cisco released fixes for a maximum severity authentication bypass vulnerability in Cisco Catalyst SD-WAN Controller (formerly vSmart) and Cisco Catalyst SD-WAN Manager (formerly vManage), tracked as CVE-2026-20127. The flaw arises from a broken peering authentication mechanism in the control-plane authentication workflow. This vulnerability potentially allows a remote, unauthenticated threat actor to bypass authentication and obtain administrative privileges on an affected system.

Episode 9 - Federal Cyber Defense: Legacy Debt, Cloud Shifts, and Network Truth

Richard Bejtlich sits down with Jean Schaffer, Corelight’s Federal CTO, to discuss the unique hurdles facing government agencies in an era of escalating state-sponsored threats. Jean highlights the persistent challenge of legacy IT infrastructure and the "technical debt" that complicates modernization efforts across the Department of Defense, the intelligence community, and the civilian sector. The conversation explores the strategic shift toward cloud adoption as a means to decommission vulnerable on-premise hardware and the evolving "whole of nation" defense strategy that requires deeper public-private partnerships.

AI Agents: How Your New Employee Brings More Security Risks

AI agents aren’t applications. They’re employees. So why are we treating them like applications? AI agents don’t behave like classic applications. They access systems. They make decisions. They operate continuously. They interact with humans and other systems without being explicitly triggered each time. That’s not automation. That’s not scripts. That’s a digital worker.

Cato CTRL Threat Research: When OpenClaw, Your AI Personal Assistant, Becomes the Backdoor

Cato CTRL’s Vitaly Simonovich (senior security researcher) has identified a threat actor selling root shell access to a UK-based automation company through a compromised AI personal assistant based on OpenClaw.

Introducing Forescout VistaroAI | The First SkillsBased Agentic AI for Cybersecurity

Meet Forescout VistaroAI, the first skills‑based agentic AI for cybersecurity. Forescout VistaroAI I thinks like a security expert, not a chatbot. It uses cybersecurity‑specific, preprogrammed skills to analyze anomalies, interpret posture changes, and automatically highlight affected assets. It eliminates the need for prompt engineering, providing role-based automation with human-in-the-loop control. The result is faster, more accurate decisions, and clearer starting points for real investigations.

Beyond Access: How Cato Measures and Manages User Risk in Real Time

On a quiet Tuesday morning, Jerry, a fictional system administrator, logged in as usual. While testing a new integration script, he visited a documentation page on an unfamiliar domain. It looked harmless and loaded without issue, but behind the scenes, Jerry’s laptop began making a series of small outbound requests to several low-reputation domains. None of these connections were malicious enough to be blocked, yet the pattern resembled early-stage domain-flux activity.

Why Every Website Should Use an IP-Based Address Geolocation Feature

Ten years ago, "Where is this visitor coming from?" was mostly a nice-to-have curiosity. In 2026, it sits at the heart of how we design conversion paths, keep pages fast, and stay compliant with regional rules like GDPR and the California Privacy Rights Act. Walk into any stand-up with a growth team and you'll hear questions about localized pricing, language toggles, and which promotions should fire for which markets. All three depend on knowing a user's location in real time. IP-based address geolocation answers that question with almost zero friction, so it remains the most widely adopted location signal on the web.
