# `CVEEPSS` type

Type `CVEEPSS` is a CVE's Exploit Prediction Scoring System (EPSS) score: the calibrated chance that exploitation activity is observed in the next 30 days. FIRST publishes a new score for every CVE daily. Use the probability for decisions and the percentile for context; most scores sit near zero because most CVEs are never exploited. Reference: [Exploit Prediction Scoring System (EPSS)](https://www.first.org/epss/)

## Fields

| Field Name | Description |
|---|---|
| `probability` - [`Float!`](https://wartiva.com/api-docs/types/float.html) | The chance, from 0 to 1, that exploitation activity is observed in the next 30 days. A score of 0.05 means about 5% of similar CVEs see exploitation activity within that window. |
| `percentile` - [`Float!`](https://wartiva.com/api-docs/types/float.html) | The share, from 0 to 1, of scored CVEs with the same or a lower probability. |
| `modelVersion` - [`String!`](https://wartiva.com/api-docs/types/string.html) | The EPSS model that produced the score, such as v2026.06.15. Scores from different models aren't comparable. |
| `scoreDate` - [`Time!`](https://wartiva.com/api-docs/types/time.html) | When EPSS scored the CVE. |

## Used by
