• epss-threshold Optional

  • The threshold value for the Exploit Prediction Scoring System (EPSS). The EPSS is a scoring system that predicts the likelihood of a vulnerability being exploited in the wild based on a time threshold. It provides a score between 0 and 1, where 0 indicates a low likelihood of exploitation, and 1 indicates a high likelihood.The action will filter out vulnerabilities that have an EPSS score below this threshold. See EPSS at https://www.first.org/epss. Default is 0.6.
