- Probability of exploitation in the next 30 days
- 0.33 %
- Percentile among all scored CVEs
- 25
- Score date
- 10/20/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
