Priority Model

Prioritize from the whole picture, not one score.

Use this model when CVSS, KEV, EPSS, public PoC, exposure, asset criticality, patch availability, and owner evidence point in different directions.

The signals that should change action order

Severity

How bad could impact be?

CVSS helps describe technical impact, but it does not prove exposure, exploitation, asset importance, or patch safety.

Exploitation

Is exploitation known or plausible?

KEV, public PoC, exploit maturity, and credible reporting should accelerate validation without replacing local proof.

Exposure

Can the vulnerable path be reached?

Internet-facing, partner-facing, authenticated, internal-only, feature-disabled, or compensating-control states change the lane.

Asset Context

What business function is at risk?

Critical service, identity plane, safety process, regulated data, and blast radius can make lower scores urgent.

Patchability

Can remediation happen safely?

Fixed version, rollback, HA order, maintenance windows, vendor support, and downtime tolerance shape the action path.

Evidence Quality

How strong is the proof?

Scanner-only, owner-only, telemetry-only, vendor-only, and combined evidence should not be treated as equal.

Same severity, different priority

Critical but not reachable

A critical unauthenticated RCE affects a component that is not installed or is blocked by architecture. Priority becomes evidence closure and monitoring, not emergency patching.

Not-affected proof

Medium but identity-facing

A medium issue affects token validation on a production identity service. Priority may outrank higher CVSS items because blast radius and exposure are stronger.

Identity context

KEV but patch unsafe today

Known exploitation plus exposed asset demands action, but a risky patch window may require temporary controls, SOC monitoring, and leadership decision language.
