• Low exploitation riskCVE-2026-19400.22% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 13% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-29200.77% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 54% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-29210.87% 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-2026-29220.43% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 36% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-29230.73% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 52% of all EPSS-scored CVEs.
