Ni8mare or Noise? Evaluating the Real Risk of CVE 2026-21858

Security teams often rely on limited context when deciding which vulnerabilities demand urgent action. This webinar examines CVE 2026 21858, known as "Ni8mare," a critical unauthenticated remote code execution flaw in the n8n AI workflow automation platform with a 10.0 CVSS score. Vulnerability Intelligence analyst Mehmet Berkay Yüksel explains why, despite exploit sales and reported activity, the current assessment places it at medium risk of exploitation.

The session explores how underground intelligence, OSINT, and technical analysis help determine when a CVE shifts from theoretical concern to active threat. Attendees will gain practical methods for integrating criminal forum and marketplace monitoring into vulnerability management and prioritizing mitigation based on real threat actor activity rather than scores alone.
