CISA's Known Exploited Vulnerabilities catalog is the clearest signal in security: these CVEs are being weaponized right now. This episode breaks down what's on the list, who's at risk, and why patch age is no measure of danger.

The CISA Known Exploited Vulnerabilities (KEV) catalog cuts through the noise of endless CVE backlogs by answering one critical question: which vulnerabilities are being actively weaponized against real organizations today? This episode of CyberAttack.ai takes a close look at the current KEV snapshot, examining the patterns across enterprise platforms, the ransomware-linked entries that demand immediate attention, and why a vulnerability disclosed years ago can still be just as dangerous as a fresh zero-day. Read the full source article on the CISA Known Exploited Vulnerabilities list for the complete catalog and remediation guidance.

Here's what this episode covers:

  • What the KEV list actually means: CISA only adds a CVE when active exploitation is confirmed — not when it's theoretically dangerous — making it the most actionable triage signal available to defenders.
  • Microsoft SharePoint under siege: Four separate KEV entries across different CVE types — weak authentication, deserialization flaws, missing authentication for critical functions — underscore how deeply embedded, widely deployed platforms become prime targets.
  • A tour of the enterprise attack surface: VMware vCenter, Cisco firewalls, JetBrains TeamCity, Splunk Enterprise, Ivanti Sentry, Fortinet FortiSandbox, SonicWall, and Adobe ColdFusion all appear, reflecting attackers' preference for high-ROI infrastructure rather than obscure edge cases. Continuous vulnerability management is the only reliable way to stay ahead of this moving target.
  • Ransomware-tagged entries: A dedicated subset of KEV listings — including SonicWall SMA, Check Point Security Gateways, Oracle PeopleSoft, PTC Windchill, Palo Alto PAN-OS, and Progress MOVEit — are directly tied to ransomware campaigns, raising the stakes for any organization running those products.
  • Log4Shell is still on the list: CVE-2021-44228, disclosed in late 2021, remains actively exploited in 2026 — proof that attackers run on opportunism and maintain persistent lists of unpatched systems regardless of a CVE's age.
  • Turning intelligence into action: CISA assigns most KEV entries a 72-hour remediation window for federal agencies — a signal private-sector security teams and boards should treat as a benchmark, not a footnote. Cross-referencing the KEV feed against your asset inventory through attack surface monitoring is the practical first step.

Pair the catalog with incident response planning for any listed flaw already present in your environment.

What is CyberAttack.ai?

AI cybersecurity and risk management for teams that have to prove their posture, not just describe it. Vulnerability management, detection engineering, compliance frameworks, vendor and third-party risk, and how automation changes the work of a small security function.

Each episode takes one problem — triaging a vulnerability backlog nobody can finish, evidence collection for an audit, what to do about a supplier that won't answer your questionnaire — and works through a practical approach. Written for security leads and the IT teams carrying security alongside everything else. Five or six minutes, one topic, no vendor FUD.

Topics include vulnerability triage and backlog reality, detection engineering, compliance evidence collection, third-party and vendor risk, incident response for small teams, identity and access hygiene, and where security automation earns its keep.
