TL;DR: CVE triage breaks down when teams rely on CVSS alone, because severity scores do not show whether a flaw is actively exploited or trending toward exploitation. Senserva’s analysis argues for combining CISA KEV, EPSS, exposure age, and fleet scope so remediation can be defended to both auditors and operators.
Editorial analysis by NHI Mgmt Group, based on content published by Senserva: “The CVE List Isn't the Hard Part”.
Key questions
A: Security teams should treat CVE scores as one input, not the decision.
Q: Why do KEV and EPSS give better vulnerability signals than CVSS alone?
A: KEV shows what is already being exploited in the wild, while EPSS estimates which flaws are likely to be exploited soon.
Q: What breaks when low-severity vulnerabilities are only triaged one by one?
A: Teams lose sight of attacker behaviour.
Practitioner guidance
- Prioritise KEV-listed vulnerabilities first Place CISA KEV-confirmed items at the top of your remediation queue, then sequence the rest by exploit likelihood and business exposure instead of by severity score alone.
- Add EPSS to your triage workflow Use EPSS as a daily-changing signal to separate immediate patch work from vulnerabilities that are likely to become relevant soon but are not yet confirmed in KEV.
- Weight patch age and fleet scope Rank findings higher when the exposure has been open longer or when the vulnerable build is present across more endpoints, because both factors increase operational risk.
Bottom line: CVSS alone is not enough to decide what to fix first because it does not show active exploitation or likely attack timing.

CVSS-only triage is a governance failure, not a tooling gap. The score tells teams how severe a vulnerability looks in isolation, but it does not establish whether the flaw is already being exploited or whether it is material in the current fleet. That leaves security and operations teams with an apparent list but no defensible order of operations. The implication is that vulnerability governance has to be judged on decision quality, not on the volume of findings.
A question worth separating out:
Q: How should auditors evaluate a prioritised patch plan?
A: Auditors should look for a repeatable triage method that combines exploitation evidence, likelihood, exposure age, and asset scope. A defensible plan shows why one flaw was patched first and another waited, rather than claiming everything was critical. That approach demonstrates governance, not just inventory management.
