Exploitation outlook

EPSS (FIRST.org) estimates each CVE’s probability of exploitation in the next 30 days — here is the CSIRTS.com read on those numbers.

• Moderate exploitation riskCVE-2026-227091.2% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 67% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-241180.91% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 58% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-241200.90% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 57% of all EPSS-scored CVEs.
• Moderate exploitation riskCVE-2026-247811.2% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 66% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-263320.71% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 51% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-269560.92% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 58% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-439970.98% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 60% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-439990.97% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 60% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-440000.20% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 10% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-440010.45% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 38% of all EPSS-scored CVEs.
