EPSS V4 arrives March 17 with new insights on real-world exploit likelihood. Preliminary data shows moderate score shifts, though outliers exist, including a puzzling jump for CVE-2007-4559. Binned distributions reveal minimal changes near the lower end, often tied to unverified exploits, while bug bounty activity and threat feeds help validate higher-risk flaws. Ransomware campaigns frequently target vulnerabilities with high EPSS scores, reminding security teams that a single metric rarely provides the full picture. ASPM, application security reviews, and ongoing remediation efforts round out a more comprehensive approach. This holistic method considers bug bounty reports, active scanning, and real-time intel, ensuring that unknown zero-day threats are not overlooked.
