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-2026-283860.31% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 24% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-283870.67% 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-2026-283880.89% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 57% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-283890.80% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 55% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-283900.80% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 55% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-317890.24% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 15% of all EPSS-scored CVEs.
- Moderate exploitation riskCVE-2026-317901.0% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 62% of all EPSS-scored CVEs.
