Summary

Endor Labs' tutorial on prioritizing open-source software (OSS) vulnerabilities focuses on using reachability analysis to identify and address the most critical issues. The method involves scanning for OSS vulnerabilities and operational risks, utilizing program analysis to pinpoint which risks are reachable, and illustrating these risks through call paths from code to vulnerable functions. By evaluating factors such as severity, Exploit Prediction Scoring System (EPSS), patch availability, and reachability, the process helps filter thousands of vulnerabilities down to the most urgent five. The tutorial was initially published on November 9, 2023, and later updated on August 25, 2025, emphasizing the evolving nature of OSS security practices.
