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-2025-50633.6% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 89% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2025-50640.34% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 26% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2025-50650.43% 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-2025-50660.43% 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-2025-50670.38% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 31% of all EPSS-scored CVEs.
• Moderate exploitation riskCVE-2025-52802.8% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 86% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2025-52810.24% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 15% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2025-52830.64% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 48% of all EPSS-scored CVEs.
