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.

• Moderate exploitation riskCVE-2026-23134.3% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 90% of all EPSS-scored CVEs.
• Moderate exploitation riskCVE-2026-23144.4% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 91% of all EPSS-scored CVEs.
• Moderate exploitation riskCVE-2026-23158.6% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 95% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-23160.23% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 14% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-23170.21% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 11% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-23180.23% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 14% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-23190.21% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 11% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-23200.22% 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-2026-23210.25% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 17% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-23220.23% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 14% of all EPSS-scored CVEs.
