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-2026-533590.96% 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-2026-533600.24% 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-2026-533610.13% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 3% of all EPSS-scored CVEs.
- Exploitation confirmedCVE-2026-53362Already exploited in the wild (CISA KEV) — the prediction phase is over. Patch now. Riskier than 41% of all EPSS-scored CVEs.
