## 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:** 2.21.0
- **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 entry points and package metadata match an authentication SDK, with no install hooks or fixed unrelated network destination identified. Requests use the configured auth domain, and token handling and session refresh match the stated purpose.

## Latest scan

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 identified; the package implements an authentication client.

- **Trigger:** Consumers import the library and create a client to use its authentication features.

- **Impact:** Expected authentication traffic and session storage for the caller’s application.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T14:31:15.096Z

### AI review details

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

- **Mechanism:** Authentication requests use the configured domain, with tokens supplied to request helpers and session state managed through the documented storage adapters.

- **Rationale:** The entry points and package metadata match an authentication SDK, with no install hooks or fixed unrelated network destination identified. Requests use the configured auth domain, and token handling and session refresh match the stated purpose.

### Review decision

- **Verdict:** Clean

- **Confidence:** 97.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** Package metadata exposes the main and Next.js authentication library entry points, marks the package side-effect-free, and declares no lifecycle scripts., The client normalizes the caller-provided domain and uses it as the issuer, rather than selecting a fixed unrelated host., Authorization headers are built from tokens supplied to the request helper, consistent with normal authenticated API calls., The README describes OAuth, passwordless login, token refresh, and browser storage as the package’s purpose.

- **Evidence against:** The library handles access tokens and persists authentication state in browser storage, which is expected for an authentication client., Creating a client initializes session handling; this behavior is part of the documented authentication flow.

## Affected versions and remediation
