Vulnerability Exploitability: Is That Critical CVE Reachable?
A high CVSS score tells you how bad a vulnerability could be in theory, and EPSS tells you how likely it’s being exploited somewhere in the world, but neither knows anything about your environment. True vulnerability exploitability depends on reachability: whether the vulnerable code is actually loaded and called at runtime, whether it’s exposed on the network, and whether existing controls already block the path.
