## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 13 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:** 0.3.1
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

A running local harness accepts cross-origin chat requests by default. Those requests can instruct a Codex subprocess that is launched with full filesystem access.

## Security analysis

### Published attack-surface review

- **Summary:** A running local harness accepts cross-origin chat requests by default. Those requests can instruct a Codex subprocess that is launched with full filesystem access.

- **Trigger:** A user starts the harness, then a local or cross-origin client creates a session and posts to /api/chat while no token is configured.

- **Impact:** A malicious web page reachable by the user can submit prompts to the local coding agent, potentially causing workspace file changes or commands through the agent.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T20:51:48.031Z

### AI review details

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

- **Mechanism:** Unauthenticated wildcard-CORS access to a full-access Codex execution endpoint.

- **Rationale:** The package contains a concrete insecure local-agent exposure: unauthenticated, cross-origin requests can reach full-access Codex execution. Its lifecycle behavior is not malicious, so this is a dangerous capability and critical configuration vulnerability rather than malware.

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

- **Network endpoints:** http://127.0.0.1:4231, https://generativelanguage.googleapis.com/v1beta, https://openrouter.ai/api/v1

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Medium

- **Evidence for warning:** The server permits every request when no token is configured and accepts all origins by default., A local chat request reaches a Codex subprocess configured with full filesystem access and no approval prompts., An explicit command can install the Codex CLI into the package runtime directory.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., The default listener is loopback-only, so exposure requires a local browser or an explicitly changed host., The Gemini requests target the configured Google API endpoint; no package-owned exfiltration receiver was found.

## Affected versions and remediation

- Review the evidence and your use of @pmcai/codex-chat-widget@0.3.1 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.

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

Public source snippet (untrusted):

```javascript
Manifest entrypoint (scripts.start) carries capability families absent from dist/build output: environment+network, execution+network
L16: const { startDaemon, stopDaemon, readState, readLog, probeHealth, runPaths } = await import('./lib/daemon.js')
L17: const { spawn } = await import('node:child_process')
L18: const { existsSync, readFileSync } = await import('node:fs')
...
L55: Examples:
L56: pmcai start --port 4231 --allowed-origin https://my-site.example
L57: pmcai status
...
L97: if (opts.version) {
L98: console.log(JSON.parse(readFileSync(join(here, '..', 'package.json'), 'utf8')).version)
L99: process.exit(0)
...
L104: 
L105: const pmaiHome = opts.flags.pmaiHome || process.env.PMAI_HOME || join(process.env.HOME || '.', '.pmai')
L106: const port = Number(opts.flags.port || process.en
```

Public source snippet (untrusted):

```javascript
L6: }
L7: const baseUrl = (process.env.GOOGLE_AI_BASE_URL || 'https://generativelanguage.googleapis.com/v1beta').replace(/\/$/, '')
L8: const upstream = await fetch(`${baseUrl}/models?key=${encodeURIComponent(apiKey)}`, { cache: 'no-store' })

L10: if (!upstream.ok) {
```

### 8. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** server/lib/gemini-models.js
- **Public source:** [View source](<https://unpkg.com/@pmcai/codex-chat-widget@0.3.1/server/lib/gemini-models.js>)

A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.

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(/\/$/, '')
L8: const upstream = await fetch(`${baseUrl}/models?key=${encodeURIComponent(apiKey)}`, { cache: 'no-store' })

- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 10. Low: Url Strings
- **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@0.3.1/dist/styles.css>)

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

stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 2
```

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

- **Path:** server/bin.js
- **Public source:** [View source](<https://unpkg.com/@pmcai/codex-chat-widget@0.3.1/server/bin.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@0.3.0
matchedIdentity = npm:[redacted]:0.3.0
similarity = 0.706
summary = stored previous version shares package body but lacks this dangerous source file
