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-2026-563500.26% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 17% of all scored CVEs.
Low exploitation riskCVE-2026-563600.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 8% of all scored CVEs.
Moderate exploitation riskCVE-2026-274931.1% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 61% of all scored CVEs.
Low exploitation riskCVE-2026-274940.35% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 27% of all scored CVEs.
Low exploitation riskCVE-2026-274950.60% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 44% of all scored CVEs.
Low exploitation riskCVE-2026-274970.77% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 51% of all scored CVEs.
Low exploitation riskCVE-2026-274980.72% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 49% of all scored CVEs.
Elevated exploitation riskCVE-2026-2757710.2% 30-day exploitation probability — well above the norm. Schedule remediation this cycle. Riskier than 95% of all scored CVEs.
Low exploitation riskCVE-2026-275780.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 8% of all scored CVEs.
