## Security analysis

### Published attack-surface review

- **Summary:** A postinstall hook runs during global npm installation. It executes a remote shell installer and adds and installs a Codex plugin without an explicit user command or confirmation.

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

- **Impact:** It changes the user's Codex installation and enables code from a Git marketplace repository to run in the agent environment.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-31T15:36:56.425Z

### AI review details

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

- **Mechanism:** Automatic remote shell execution and Codex marketplace/plugin installation.

- **Attack narrative:** Installing this package globally invokes its postinstall script. The script conditionally downloads and pipes a remote installer to sh, then adds a Git marketplace and installs a Codex plugin. These actions occur automatically during installation and modify a broad AI-agent control surface, allowing additional marketplace code to become active.

- **Rationale:** The automatic postinstall chain performs remote code installation and unconsented Codex plugin configuration. Its global-install guard narrows exposure but does not establish user consent for these mutations.

- **Files touched:** ~/.codex/packages/standalone/current/codex, ~/.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 npm postinstall hook automatically runs a global installer., On global install, it downloads and executes a remote shell installer without user confirmation., The same hook adds a Git marketplace and installs a Codex plugin, mutating the user's agent control surface.

- **Evidence against:** The hook is limited to global npm installs and skips CI, Windows, and ordinary dependency installs., The runtime wrapper asks before its separate managed-Codex installation path.
