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.

• Low exploitation riskCVE-2026-271420.33% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 26% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-338110.81% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 55% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-338140.78% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 54% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-398170.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 7% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-398190.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 8% of all EPSS-scored CVEs.
