## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. A package installation can execute remote code and add a third-party plugin to the user's Codex environment.

- **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:** 3.21.3
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. On global npm installation, the postinstall script installs a managed Codex build and modifies Codex's plugin marketplace and installed plugins. These are unconsented changes to an external AI-agent control surface.

## Security analysis

### Published attack-surface review

- **Summary:** On global npm installation, the postinstall script installs a managed Codex build and modifies Codex's plugin marketplace and installed plugins. These are unconsented changes to an external AI-agent control surface.

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

- **Impact:** A package installation can execute remote code and add a third-party plugin to the user's Codex environment.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-01T10:12:50.576Z

### AI review details

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

- **Mechanism:** Lifecycle-driven remote shell installation and Codex plugin registration.

- **Attack narrative:** Installing the package globally triggers its postinstall hook. The hook invokes a shell command that downloads and executes an installer from chatgpt.com, then uses the local Codex CLI to add a marketplace from GitHub and install the Cogent plugin. The script only runs for global installs, but it performs these changes automatically rather than through an explicit setup command.

- **Rationale:** The global postinstall hook mutates a foreign, broad AI-agent control surface and executes a remote installer without consent. Its guards limit exposure but do not remove the concrete install-time behavior.

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

- **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 package automatically runs a postinstall script., The script activates during global installation without an interactive consent prompt., It pipes a remote installer into a shell to install Codex., It adds a third-party marketplace and installs its Cogent plugin into Codex.

- **Evidence against:** The lifecycle script skips dependency, CI, Windows, and ordinary non-global installs., The command-line wrapper asks before its separate runtime installer path.
