The Common Vulnerability Scoring System (CVSS) is a standardized framework for assessing the severity of security vulnerabilities. It helps organizations prioritize vulnerability patching by providing a numerical score that reflects the potential impact and exploitability of a vulnerability. CVSS scores are used to gauge the urgency of patching vulnerabilities within a company's IT environment.
