A global npm postinstall silently provisions a managed Codex build and installs a Codex plugin. It retrieves executable installer content over the network and mutates the user-wide Codex control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-08-23T14:06:20.689Z - **Finished:** 2026-08-23T14:07:23.201Z - **Download time:** 759 ms - **Static scan time:** 919 ms - **AI review time:** 60833 ms - **Total time:** 62512 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm postinstall silently provisions a managed Codex build and installs a Codex plugin. It retrieves executable installer content over the network and mutates the user-wide Codex control surface. - **Trigger:** npm install -g @essentialai/cogent-bridge - **Impact:** Unconsented execution of remote installer code and user-wide AI-agent extension installation. - **Evidence paths:** package.json, scripts/postinstall-global.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T14:07:23.201Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote shell installer plus Codex plugin registration - **Attack narrative:** On global installation, npm invokes a hook that executes a curl-piped shell installer from chatgpt.com and then invokes Codex to add a marketplace and install a plugin. The behavior is gated to global installs but is automatic once triggered, affecting user-wide Codex state rather than only this package's files. - **Rationale:** The package’s install hook performs unprompted remote-code installation and alters the broad, foreign Codex agent surface. This meets the blocking policy despite vendor-aligned endpoints. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** ~/.codex/packages/standalone - **Network endpoints:** https://chatgpt.com/codex/install.sh, https://github.com/eaisdevelopment/cogent.git ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall runs a global-install setup script., That script downloads and pipes a remote Codex installer into sh., It adds a GitHub marketplace and installs a Cogent Codex plugin without a separate prompt., The setup targets Codex-managed state under ~/.codex. - **Evidence against:** The hook is gated to global installs and skips CI, Windows, and dependency installs., The plugin identifier and repository are vendor-aligned; no credential harvesting or exfiltration was confirmed. ## Public findings ### 1.
