## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 7 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:** 1.20.1
- **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.

The package’s entry point only re-exports SDK functionality, and its authorization requests run when the application invokes a client method or middleware. The request-bound token is sent to the configured Grant API for permission checks; no unrelated credential collection or install-time behavior was found.

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 provides authorization middleware and a client for the Grant API.

- **Trigger:** An application explicitly calls an authorization method or invokes configured middleware or a guard for a request.

- **Impact:** The response is used to allow or deny the requested operation; no unrelated collection or file changes were found.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T16:09:35.290Z

### AI review details

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

- **Mechanism:** The client posts permission and resource context to the configured Grant API and may forward the token from that request.

- **Rationale:** The package’s entry point only re-exports SDK functionality, and its authorization requests run when the application invokes a client method or middleware. The request-bound token is sent to the configured Grant API for permission checks; no unrelated credential collection or install-time behavior was found.

- **Network endpoints:** \<configured apiUrl\>/api/auth/is-authorized (example host: api.grant.com)

### Review decision

- **Verdict:** Clean

- **Confidence:** 98.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package exposes server-side authorization SDK entry points and declares build, lint, and test scripts, with no install lifecycle script., The main ESM entry point only imports and re-exports the Grant client and error types., The client sends a POST to /api/auth/is-authorized when an authorization check is called., Requests use the configured apiUrl; a token is extracted from the supplied request and forwarded as a Bearer token.
