• Low exploitation riskCVE-2025-433250.21% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 11% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-206720.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 8% of all EPSS-scored CVEs.
• Elevated exploitation riskCVE-2026-2391849.7% 30-day exploitation probability — well above the norm. Schedule remediation this cycle. Riskier than 99% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-288490.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 6% of all EPSS-scored CVEs.
