Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A global npm installation automatically modifies the user's Codex environment. It downloads and executes a remote shell installer, then adds a marketplace and installs a Codex plugin. - **Trigger:** npm install -g @essentialai/cogent-bridge on a non-CI Unix system - **Impact:** Unconsented code execution from a remote installer and mutation of the user's AI-agent control surface. - **Evidence paths:** package.json, scripts/postinstall-global.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T07:45:35.359Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall remote shell execution and automatic Codex plugin installation - **Attack narrative:** The postinstall lifecycle hook activates automatically during a global install. It invokes a shell pipeline that downloads an installer from chatgpt.com and executes it, then uses the Codex CLI to add a marketplace and install a plugin. These actions alter a separate AI-agent installation without an explicit setup command or confirmation. - **Rationale:** The global-install guard limits exposure, but it does not provide consent for an npm lifecycle hook to execute downloaded shell code and modify the user's Codex installation. This is concrete install-hook abuse of a foreign AI-agent control surface. - **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:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares an automatic postinstall lifecycle hook., On global install, the hook pipes a remote installer into sh without a confirmation., The same hook automatically adds a Codex marketplace and installs its plugin., The install script pipes a remote Codex installer directly into sh. - **Evidence against:** The hook is guarded to global npm installs and skips CI and Windows., The manifest has no runtime dependency on this package's own name. ## Affected versions and remediation This report applies to @essentialai/cogent-bridge@3.23.9. - Avoid installing @essentialai/cogent-bridge@3.23.9. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
