## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 20 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 1.0.775
- **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.

Inspected source does not establish credential theft, unconsented agent configuration mutation, or another concrete attack. Because static analysis reports parse errors in several executable modules, the remaining uncertainty warrants a warning rather than a clean verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 62.0%
- **Started:** 2026-10-09T05:23:19.232Z
- **Finished:** 2026-10-09T05:24:20.250Z
- **Download time:** 1526 ms
- **Static scan time:** 3666 ms
- **AI review time:** 55825 ms
- **Total time:** 61018 ms

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 concrete attack was established from the inspected source. Incomplete static analysis leaves behavior in several executable modules unresolved.

- **Trigger:** No malicious trigger was confirmed; the postinstall hook invokes the PATH helper, while MCP and login behavior run through CLI use.

- **Impact:** The unresolved analysis prevents confirming that all executable behavior is benign; no specific harmful effect was verified.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T05:24:20.250Z

### AI review details

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

- **Mechanism:** The examined MCP path requires project approval, and the examined login path sends a worker key to the selected API base. Parse errors in other modules limit confidence in a package-wide assessment.

- **Rationale:** Inspected source does not establish credential theft, unconsented agent configuration mutation, or another concrete attack. Because static analysis reports parse errors in several executable modules, the remaining uncertainty warrants a warning rather than a clean verdict.

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 62.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** \`mcp-config.mjs\` reads \`.mcp.json\`; project servers require saved per-project approval before they are runnable., \`gu-cli.mjs\` calls the MCP configuration when assembling agent job settings., \`gu-repl.mjs\` starts device login only when credentials are missing and the terminal is interactive., \`device-login.mjs\` sends the worker key to the selected API base for a settings check., \`package.json\` runs a PATH helper at postinstall; its main function skips Windows and CI., Static analysis reports parse errors in several executable modules, leaving some behavior unresolved.

- **Evidence against:** The inspected MCP logic gates project servers on saved approval; no unconsented project server execution was established., The inspected credential flow sends the key to the configured worker API; no unrelated recipient or hidden forwarding was established.

- **Path:** gu-repl.mjs
- **Public source:** [View source](<https://unpkg.com/@tiens.nguyen/gu-cli@1.0.775/gu-repl.mjs>)

Manifest-reachable source sends a prompted API credential to a fixed unofficial gateway and persists the redirection.

Public source snippet (untrusted):

```javascript
Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration.
gu-repl.mjs:
import { readFile, mkdir, writeFile, unlink, rename } from "node:fs/promises";
import { existsSync, statSync, readFileSync, writeFileSync, readdirSync, openSync, readSync, closeSync } from "node:fs";
import { createInterface } from "node:readline";
// A SELF-CONTAINED prompt: this runs before the REPL's readline (and its ask()) is
// ONE readline for the whole first run: the mode question and the key prompt share it,
// the REPL's own readline exists, so it owns the terminal here).
const rl0 = (await import("node:readline")).createInterface({
// Exit AFTER the readline is closed, so the terminal is left in a usable state.
```

### 12. High: Sandbox Evasion Gated Capability
- **Category:** Source
- **Confidence:** 84.0%
- **Path:** gu-cli.mjs
- **Public source:** [View source](<https://unpkg.com/@tiens.nguyen/gu-cli@1.0.775/gu-cli.mjs>)

Source gates dangerous network, credential, or execution behavior behind CI, host, platform, time, or geo fingerprint checks.

Public source snippet (untrusted):

```javascript
L18: import { mkdir, mkdtemp, readFile, rm, stat, unlink, writeFile } from "node:fs/promises";
L19: import { execFile as execFileCallback, spawn } from "node:child_process";
L20: import { createHash, randomUUID } from "node:crypto";
...
L75: 
L76: // Running worker version, read from the package's own package.json (single source of
L77: // truth) so the startup banner shows exactly which build a box is running (task #105).
...
L88: 
L89: const ENV_FILE = join(homedir(), ".gonext", "worker.env");

- **Path:** coding-provider-setup.mjs
- **Public source:** [View source](<https://unpkg.com/@tiens.nguyen/gu-cli@1.0.775/coding-provider-setup.mjs>)

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";

```

### 20. High: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** client-expert-api.mjs
- **Public source:** [View source](<https://unpkg.com/@tiens.nguyen/gu-cli@1.0.775/client-expert-api.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@1.0.692
matchedIdentity = npm:QHRpZW5zLm5ndXllbi9ndS1jbGk:1.0.692
similarity = 0.595
summary = stored previous version shares package body but lacks this dangerous source file
