The First EPSS Calculator is an open-source tool designed to fetch and display the Exploit Prediction Scoring System (EPSS) score for one or multiple CVEs (Common Vulnerabilities and Exposures). The calculator provides detailed information such as the EPSS score—which estimates the probability that a given vulnerability will be exploited in the next 30 days—along with supporting data like available patches, known exploits, and vulnerability summaries. By leveraging machine learning and real-world exploit data, the EPSS Calculator helps security professionals prioritize remediation efforts by highlighting which vulnerabilities are most likely to be exploited soon.
The last publication date of the FIRST EPSS (Exploit Prediction Scoring System) Calculator and model is March 17, 2025, when EPSS Version 4 was released. This version introduced major improvements including better data modeling for more accurate exploit predictions and real-time tracking of exploit activity to reflect current threats
