How to prioritize third-party package (SCA) vulnerabilities

Prioritizing third-party package (SCA) vulnerabilities requires tools and processes that enable accurate severity and exploitability assessments, considering the context surrounding each vulnerability. Common Vulnerability Scoring System (CVSS), Known Exploited Vulnerabilities (KEV) catalog, and Exploit Prediction Scoring System (EPSS) are useful tools for prioritizing vulnerabilities but lack critical contextual information about how different dependencies will affect a specific product or business. To effectively prioritize third-party package vulnerabilities, it is essential to understand the business importance of projects and assets, as well as the unique organizational context surrounding each threat.
