## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. An npm lifecycle hook modifies a broad AI-agent control surface and installs code from remote sources without an explicit user command or confirmation.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 3.21.5
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. A global npm install automatically changes the Codex installation and plugin configuration. It downloads and executes a remote shell installer, then adds a third-party marketplace and plugin.

## Security analysis

### Published attack-surface review

- **Summary:** A global npm install automatically changes the Codex installation and plugin configuration. It downloads and executes a remote shell installer, then adds a third-party marketplace and plugin.

- **Trigger:** npm install -g @essentialai/cogent-bridge

- **Impact:** An npm lifecycle hook modifies a broad AI-agent control surface and installs code from remote sources without an explicit user command or confirmation.

- **Evidence paths:** package.json, scripts/postinstall-global.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-01T14:55:24.354Z

### AI review details

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

- **Mechanism:** Postinstall remote shell execution and automatic Codex plugin provisioning.

- **Attack narrative:** Installing the package globally invokes its postinstall hook. The hook silently proceeds when the Codex managed build is absent, fetches an installer from chatgpt.com and pipes it to sh, then registers a GitHub marketplace and installs the cogent plugin into Codex. These actions alter the user's AI-agent runtime during package installation rather than through a separately invoked setup command.

- **Rationale:** The automatic global-install hook performs remote shell execution and unconsented Codex marketplace/plugin mutation. Its guards limit scope but do not provide user consent for this broad control-surface change.

- **Files touched:** ~/.codex/packages/standalone, scripts/postinstall-global.mjs

- **Network endpoints:** https://chatgpt.com/codex/install.sh, https://github.com/eaisdevelopment/cogent.git

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** The manifest runs a postinstall script automatically., On global installation, the script pipes a remotely fetched installer directly to sh without a confirmation prompt., The same postinstall automatically adds a Git marketplace and installs a Codex plugin.

- **Evidence against:** The lifecycle script skips dependency, npx, CI, and Windows installs., No credential harvesting or data-exfiltration behavior was established in the inspected install path.
