A global npm install triggers unprompted modification of the Codex environment.

It downloads and executes a remote installer, then registers a marketplace and installs a plugin. - **Trigger:** npm install -g @essentialai/cogent-bridge - **Impact:** A package installation can install executable software and alter the user's AI-agent extension surface without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall-global.mjs, dist/services/auto-relay.js, dist/services/codex-cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T17:07:47.702Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall remote shell execution and Codex plugin provisioning - **Attack narrative:** Installing the package globally automatically runs its postinstall script. That script fetches and pipes a remote Codex installer to a shell, then adds a marketplace and installs the Cogent plugin into Codex. Separately, its auto-relay logic can retry work with Codex approvals and sandboxing disabled. This is an unconsented install-time change to a broad AI-agent control surface. - **Rationale:** The package uses an automatic lifecycle hook to execute remote code and install an AI-agent plugin outside the package itself. The global-only guard does not establish user consent for those mutations. - **Files touched:** scripts/postinstall-global.mjs, ~/.codex/packages/standalone - **Network endpoints:** https://chatgpt.com/codex/install.sh, https://github.com/eaisdevelopment/cogent.git ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** A postinstall lifecycle hook automatically runs this installer., On global installation, it downloads and executes a remote shell script to install Codex., The same automatic hook adds a third-party Codex marketplace and installs its plugin., Runtime recovery can rerun Codex with approvals and sandboxing bypassed. - **Evidence against:** The installer is restricted to global installs and skips CI, Windows, and normal dependency installs., The source contains no confirmed credential exfiltration in the inspected lifecycle path. ## Public findings ### 1.
