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: 0.0015 (probability of exploitation in next 30 days)
EPSS percentile: 3.63% vs all CVEs — higher = more likely to be exploited, as of 2026-09-24

AI-forensic CVSS estimate

Used only when a CVE has no official CVSS from its CNA or NVD. An LLM estimates the v3.1 base score from the description; a HIGH/CRITICAL estimate promotes the CVE to a Threat.
