EPSS Score Checker

Help & Information

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

  • EPSS Score: A value between 0 and 1 (0% to 100%). The higher the score, the greater the probability of a vulnerability being exploited.
  • Percentile: Indicates how a vulnerability's EPSS score compares to all other scored vulnerabilities. A 95% percentile means the vulnerability is more likely to be exploited than 95% of other vulnerabilities.
  • CWE (Common Weakness Enumeration): A category system for software weaknesses and vulnerabilities.
  • Bulk Operations: Use the "Bulk Results" tab to filter, sort, and select CVEs for comparison or export. Click any successful row to see its detailed view.
