# CVE Validation

## Domain

Validate candidate CVEs against the current target evidence without assuming exploitability.
The module consumes `cve_candidate_list`, product/version evidence, service fingerprints, and scope data, then decides whether the CVE path is usable, patched, not applicable, or needs more recon.

## Trigger

```text
cve_candidate_list_ready
```

## Feedback Gates

- Scope Gate: target and asset must be in the declared authorization boundary.
- Evidence Gate: candidate CVE must map to observed product, version, endpoint, service, or fingerprint evidence.
- Applicability Gate: version range, configuration, and reachable component must plausibly match.
- Patch Gate: observed version or vendor advisory must not prove the issue fixed.
- Execution Gate: active validation requires a registered scoped adapter; missing adapters block rather than pretending execution happened.

## Boundaries

- Do not run destructive or broad exploit attempts.
- Do not validate outside the declared target and scope.
- Do not treat CVE names alone as proof.
- Prefer passive or low-noise confirmation first.
- If evidence is insufficient, return to recon or CVE lookup rather than guessing.

## Pivot Hints

- Candidate has no product/version match -> return to recon-intake for better fingerprinting.
- Candidate is patched or not applicable -> route by highest-ranked attack surface from recon.
- Tool or adapter missing -> record missing capability and request/choose an equivalent adapter.
- Too many candidates -> rank by reachable component, confidence, impact, and version fit.

## Exit Conditions

- Confirmed applicable candidate -> continue to the specific validation/testing skill.
- All candidates patched/not applicable -> exit to evidence-based router.
- Evidence incomplete -> return to recon-intake or cve-lookup.
- Required tool/scope/adapter missing -> block with the missing capability or scope evidence.

## Exit Evidence

- Required: cve_validation_result
- Optional: cve_patch_status, applicability_proof, non_applicability_reason
- min_attempts: 1

## Capabilities

cve_applicability     -> cve_validation_result
patch_status_check    -> cve_patch_status
