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-2026-216360.69% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 50% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-486150.42% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 35% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-486170.32% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 25% of all EPSS-scored CVEs.
- Moderate exploitation riskCVE-2026-486183.2% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 87% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-486190.64% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 48% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-489280.22% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 12% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-489300.32% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 25% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-489310.34% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 28% of all EPSS-scored CVEs.
- Moderate exploitation riskCVE-2026-489333.7% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 89% of all EPSS-scored CVEs.
