dependency-check-core is the engine and reporting tool used to identify and report if there are any known, publicly disclosed vulnerabilities in the scanned project's dependencies. The engine extracts meta-data from the dependencies and uses this to do fuzzy key-word matching against the Common Platfrom Enumeration (CPE), if any CPE identifiers are found the associated Common Vulnerability and Exposure (CVE) entries are added to the generated report.
