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

• Low exploitation riskCVE-2026-321750.71% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 50% of all scored CVEs.
• Low exploitation riskCVE-2026-321770.55% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 43% of all scored CVEs.
• Low exploitation riskCVE-2026-354330.66% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 48% of all scored CVEs.
• Low exploitation riskCVE-2026-410940.84% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 54% of all scored CVEs.
