## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.2.0
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

## Security analysis

### Published attack-surface review

- **Summary:** The explicitly started local harness accepts cross-origin requests without a default token and forwards prompts to an unrestricted Codex process. This is a concrete local agent-abuse and remote-code-execution risk, not an install-time payload.

- **Trigger:** A user starts the CLI or server, then a browser or local client creates a session and posts to /api/chat.

- **Impact:** An untrusted web page can potentially cause Codex to execute commands and modify files accessible to its process.

- **Evidence paths:** server/lib/cors.js, server/index.js, server/lib/runner.js, server/codex.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T20:35:17.674Z

### AI review details

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

- **Mechanism:** Unauthenticated cross-origin prompt forwarding to Codex with danger-full-access.

- **Rationale:** The package exposes an unauthenticated, cross-origin route to a full-access coding agent, creating a serious user-triggered capability abuse risk. Its dangerous actions occur only after explicit runtime use rather than through an install hook, so the source does not establish malware.

- **Files touched:** ~/.pmai/workspace, ~/.pmai/.codex-runs, ~/.pmai/node\_modules

- **Network endpoints:** 127.0.0.1

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 96.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The runtime server permits all origins and treats an absent token as authorized., An unauthenticated chat request is passed to a Codex turn., The turn launches Codex with unrestricted sandbox access., The CLI can install the Codex package during explicit runtime setup.

- **Evidence against:** There is no preinstall, install, or postinstall hook; the listed lifecycle scripts only invoke a build file., The package does not contain a self-dependency or an observed secret-exfiltration receiver., Google and OpenRouter requests implement selected provider functionality rather than a hidden receiver.

## Affected versions and remediation

Manifest entrypoint contains risky behavior absent from dist/build output.

Public source snippet (untrusted):

```javascript
Manifest entrypoint (manifest.exports) carries capability families absent from dist/build output: environment+network, execution+network
L5: // Serves the same API the browser widget expects, plus a built-in login page, so one
L6: // command gives you a working Codex chat on http://127.0.0.1:4231.
L7: import { createServer } from 'node:http'
...
L30: if (!chunks.length) return {}
L31: return JSON.parse(Buffer.concat(chunks).toString('utf8'))
L32: }
...
L36: res.writeHead(status, { 'content-type': 'application/json; charset=utf-8', 'content-length': Buffer.byteLength(payload), ...extraHeaders })
L37: res.end(payload)
L38: }
...

Public source snippet (untrusted):

```javascript
Trigger-reachable chain: manifest.exports -> server/index.js -> server/lib/gemini-models.js
L6: }
L7: const baseUrl = (process.env.GOOGLE_AI_BASE_URL || 'https://generativelanguage.googleapis.com/v1beta').replace(/\/$/, '')

- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 11. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 12. High: Semantic Analysis Limited
- **Category:** Scanner Coverage
- **Confidence:** 100.0%
- **Path:** dist/styles.css
- **Public source:** [View source](<https://unpkg.com/@pmcai/codex-chat-widget@0.2.0/dist/styles.css>)

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

```

### 13. Critical: Previous Version Dangerous Delta
- **Category:** Supply Chain

- **Path:** server/lib/runner.js
- **Public source:** [View source](<https://unpkg.com/@pmcai/codex-chat-widget@0.2.0/server/lib/runner.js>)

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 = @pmcai/codex-chat-widget@0.1.0
matchedIdentity = npm:[redacted]:0.1.0
