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.

• Elevated exploitation riskCVE-2026-2391845.8% 30-day exploitation probability — well above the norm. Schedule remediation this cycle. Riskier than 99% of all scored CVEs.
• Low exploitation riskCVE-2026-240720.65% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 47% of all scored CVEs.
• Moderate exploitation riskCVE-2026-287801.4% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 69% of all scored CVEs.
• Low exploitation riskCVE-2026-291680.63% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 46% of all scored CVEs.
• Low exploitation riskCVE-2026-291690.59% 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-2026-330060.56% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 42% of all scored CVEs.
• Low exploitation riskCVE-2026-330070.51% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 40% of all scored CVEs.
• Low exploitation riskCVE-2026-335230.44% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 35% of all scored CVEs.
• Low exploitation riskCVE-2026-338570.39% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 31% of all scored CVEs.
• Low exploitation riskCVE-2026-340320.48% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 38% of all scored CVEs.
