• Moderate exploitation riskCVE-2020-22871.2% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 65% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-22880.95% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 59% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2020-22890.91% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 57% of all EPSS-scored CVEs.
