CVSS alone misses the real risk in vulnerability prioritization

TL;DR: Vulnerability prioritization breaks when teams rely on CVSS alone, because severity scores ignore exploitability, asset value, reachability, and compensating controls, while KEV, EPSS, and SSVC together create a more defensible remediation order, according to Crogl. Blast-radius evidence, not score sorting, is what turns backlog reduction into real risk reduction.

• The article says customers have seen a 75% reduction in analyst time per alert when evidence gathering is automated.

Key questions

Q: What breaks when vulnerability management is based only on CVSS scores?

A: CVSS-only prioritisation breaks when several lower-scoring flaws can be combined into a complete exploit path.

Q: Why do KEV and EPSS need to be used together?

A: KEV and EPSS answer different questions.

Q: What are the signs that a vulnerability is more dangerous than its score suggests?

A: The main signs are external reachability, connections into sensitive systems, privileged service accounts on the host, and compensating controls that do not fully block the attack path.

Practitioner guidance

• Prioritise KEV-listed findings first Create a separate remediation lane for vulnerabilities that are confirmed exploited in the wild and verify whether each one is reachable from an untrusted segment.
• Add reachability checks to every high-risk finding Confirm network exposure, observed traffic, and segmentation before you assign a remediation rank to a critical-scored vulnerability.
• Pull identity context into triage Review which service accounts, authenticated sessions, and elevated permissions sit on or near the vulnerable asset before you decide the blast radius.

Bottom line: Vulnerability prioritization fails when teams treat CVSS as the final answer instead of one input into an environmental risk decision.
