NVD triage scoring NVD CVE 2.0
Layer NVD adds on top of the CNA's CVE record — published / last-modified timestamps, exploitability / impact subscores, and the FIRST.org EPSS probability that this CVE will be exploited in the wild in the next 30 days.
- EPSS score
- 0.0020 (probability of exploitation in next 30 days)
- EPSS percentile
- 9.04% vs all CVEs — higher = more likely to be exploited, as of 2026-09-24
