## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 16 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 1.0.692
- **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.

This is a concrete remote code execution capability behind explicit user interaction, not proof of malicious automatic install behavior. It warrants a warning because the downloader's integrity check is controlled by the same mutable remote manifest as the payload location.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-09-12T12:52:08.798Z

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:** An interactive Client Expert setup downloads a remote archive selected by a mutable manifest, then installs its dependencies. A compromised manifest or archive source can cause npm lifecycle code from the downloaded package to execute.

- **Trigger:** The user selects Client Expert in the interactive gu terminal or runs its API upgrade workflow.

- **Impact:** Remote code execution in the invoking user's account.

- **Evidence paths:** client-expert-run.mjs, client-expert-api.mjs, gu-repl.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T12:53:16.697Z

### AI review details

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

- **Mechanism:** Remote archive download followed by npm install without a fixed trust root.

- **Rationale:** This is a concrete remote code execution capability behind explicit user interaction, not proof of malicious automatic install behavior. It warrants a warning because the downloader's integrity check is controlled by the same mutable remote manifest as the payload location.

- **Files touched:** ~/.gonext/api/\<manifest.version\>

- **Network endpoints:** gu-api-packages.s3.ap-southeast-1.amazonaws.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The Client Expert flow fetches a mutable remote manifest and follows redirects., The manifest supplies both the download URL and checksum, so the checksum is not anchored to a bundled trusted value., The package unpacks the downloaded archive under the user profile and runs npm install there without disabling lifecycle scripts., This path is reached after an interactive Client Expert choice, not during npm installation.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., The remote installer is gated behind an explicit interactive Client Expert selection., No source evidence shows credential harvesting, stealth persistence, or destructive behavior.

Public source snippet (untrusted):

```javascript
L1808: "  Usage: gu-cli embed --model ~/mlx-models/Qwen3-Embedding-8B-4bit-DWQ [--port 8085] [--host 127.0.0.1]\n" +

Source reaches cloud instance metadata or link-local credential endpoints.

Public source snippet (untrusted):

```javascript
L12: * a log means the box. An OpenAI-compatible provider is the opposite — the path is part of the
L13: * address. https://openrouter.ai/api/v1 is OpenRouter's documented base, and dropping the /api
L14: * from it 404s every call. So this keeps the path and mirrors the API's normalizeOpenAiV1Root
...
L47: if (a === 169 && b === 254) return "link-local"; // includes 169.254.169.254 (IMDS)
L48: if (a === 10) return "private";

```

### 16. High: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** gu-cli.mjs
- **Public source:** [View source](<https://unpkg.com/@tiens.nguyen/gu-cli@1.0.692/gu-cli.mjs>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @tiens.nguyen/gu-cli@1.0.686
matchedIdentity = npm:QHRpZW5zLm5ndXllbi9ndS1jbGk:1.0.686
