## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Destructive Action
- **Selected version:** 4.5.5
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The CLI contains a concrete risk of deleting existing database data without explicit confirmation. Because this occurs in the user-invoked initializer, it warrants a warning rather than a malware block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 89.0%
- **Started:** 2026-10-21T04:04:06.567Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** The explicit initializer can delete persistent database data while preparing a new container. This is a destructive setup risk.

- **Trigger:** A user runs kempo init and the CLI enters new-container setup.

- **Impact:** An existing database in the matching volume may be permanently lost.

- **Evidence paths:** bin/cli.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T04:05:18.758Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The CLI derives a Docker volume name from the database name and attempts to remove that volume without asking for confirmation.

- **Rationale:** The CLI contains a concrete risk of deleting existing database data without explicit confirmation. Because this occurs in the user-invoked initializer, it warrants a warning rather than a malware block.

- **Files touched:** bin/cli.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 89.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The manifest exposes bin/cli.js as the kempo command., The CLI exits unless the user invokes init., In new-container setup, the CLI builds a volume name from the database name and removes that volume without a deletion confirmation., The npm install kempo command runs as part of the initializer's project setup.

## Affected versions and remediation
