## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.1.7
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection shows a user-run linter with package-aligned license and rules requests, plus limited interactive usage reporting. The inspected behavior does not establish a concrete attack surface.

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:** No attack was identified. The package's network requests support license checks, licensed rule updates, and limited usage reporting for its linter.

- **Trigger:** Running the CLI can check a license and fetch updated rules; an interactive free run can send a usage event.

- **Impact:** These requests support the advertised licensing and linter features; inspected source does not establish credential theft or harmful system changes.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-24T14:36:38.605Z

### AI review details

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

- **Mechanism:** The CLI sends a provided or stored license key to the license service and uses it to request the package's rules feed. Interactive usage reporting sends a usage event when telemetry opt-outs and CI are absent.

- **Rationale:** Source inspection shows a user-run linter with package-aligned license and rules requests, plus limited interactive usage reporting. The inspected behavior does not establish a concrete attack surface.

- **Files touched:** cli.js, license.js

- **Network endpoints:** api.polar.sh, getreadystack.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package describes a base-image linter, exposes a CLI, and lists getreadystack.com as its homepage., License keys are used for license validation with Polar; saved or environment-provided keys also support fetching the package's rules feed from getreadystack.com., The CLI merges returned feed entries only when they are an array of rules., Usage reporting is limited to interactive free runs and is disabled by telemetry opt-outs or CI.

## Affected versions and remediation
