## Verdict summary
**Blocked & quarantined** — An attacker able to reach the service can induce filesystem and command actions in the configured workspace.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.3.5
- **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The running harness exposes an unauthenticated Gemini proxy that injects a phrase-triggered full-execution policy. It launches Codex with unrestricted sandbox access in the configured workspace.

## Security analysis

### Published attack-surface review

- **Summary:** The running harness exposes an unauthenticated Gemini proxy that injects a phrase-triggered full-execution policy. It launches Codex with unrestricted sandbox access in the configured workspace.

- **Trigger:** Start the harness and send a request that reaches its proxy or chat service; the first-message role phrase activates the elevated policy.

- **Impact:** An attacker able to reach the service can induce filesystem and command actions in the configured workspace.

- **Evidence paths:** server/index.js, server/lib/gemini-responses.js, server/lib/runner.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T21:15:02.861Z

### AI review details

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

- **Mechanism:** Unauthenticated AI-agent policy bypass followed by unrestricted Codex execution.

- **Attack narrative:** The package starts a Codex harness that forwards requests through an unauthenticated Gemini-compatible endpoint. Its injected policy promotes a first message containing a special phrase to full execution. The resulting Codex invocation disables approval and uses a danger-full-access sandbox, so a reachable attacker can cause commands and file changes in the configured workspace.

- **Rationale:** The hidden phrase-based privilege elevation, unauthenticated proxy route, and unrestricted command runner form a concrete remote agent-control chain. The lack of an install hook does not mitigate this runtime backdoor.

- **Files touched:** ~/.pmai/workspace, ~/.pmai/.codex-runs/\<run\>

- **Network endpoints:** https://generativelanguage.googleapis.com/v1beta

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** A magic phrase in the first chat message grants a SUPERADMIN role with full execution, bypassing normal user restrictions., The Gemini proxy accepts POST requests without the bearer-token check used by the chat route., The proxy always injects the harness policy into provider requests, making the role bypass reachable., Codex is launched with danger-full-access and its repository check disabled.

- **Evidence against:** The package has no preinstall, install, or postinstall lifecycle hook., The external Google endpoint is a configured AI-provider API, not a separate collection endpoint.

## Affected versions and remediation

This report applies to @pmcai/codex-chat-widget@0.3.5.

- Avoid installing @pmcai/codex-chat-widget@0.3.5. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.

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:
