How to calculate EPSS vulnerability score? To calculate the EPSS, you can use the publicly available JSON API by FIRST. This API enables users to connect and input a CVE number, obtaining a probability score in return. An alternative approach involves using an EPSS calculator, which grants you access to EPSS data.

The higher the score, the greater the probability that a vulnerability will be exploited. Additionally percentiles are calculated, which are a direct transformation from probabilities and provide a measure of an EPSS probability relative to all other scores.

epss : the EPSS score representing the probability [0-1] of exploitation in the wild in the next 30 days (following score publication) percentile : the percentile of the current score, the proportion of all scored vulnerabilities with the same or a lower EPSS score.

While EPSS predicts the likelihood of exploitation, CVSS measures the inherent severity of vulnerabilities. Both play crucial roles in vulnerability management but serve different purposes. CVSS scores vulnerabilities based on their characteristics and potential impacts but doesn't consider real-world threat data.

It is refreshed every day and for each published CVE. EPSS produces a probability of exploitation activity (a value between 0 and 1) in the next 30 days, which is the primary EPSS score.

VEX provides information about the applicability of vulnerabilities in specific products or environments, helping organizations understand whether a known vulnerability is relevant to their systems. EPSS, conversely, predicts the likelihood of a vulnerability being exploited regardless of specific environments.

The Exploit Prediction Scoring System (EPSS) is a data-driven effort for estimating the likelihood (probability) that a software vulnerability will be exploited in the wild.
