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-2026-261280.62% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 47% of all EPSS-scored CVEs.
- Moderate exploitation riskCVE-2026-242913.2% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 87% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-236560.30% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 22% of all EPSS-scored CVEs.
