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-2023-452290.94% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 57% of all scored CVEs.
• Moderate exploitation riskCVE-2023-452301.2% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 65% of all scored CVEs.
• Low exploitation riskCVE-2023-452310.85% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 54% of all scored CVEs.
• Moderate exploitation riskCVE-2023-452322.1% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 79% of all scored CVEs.
• Moderate exploitation riskCVE-2023-452332.1% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 79% of all scored CVEs.
