A package installation can modify the user's Codex installation and extend its agent control surface without an explicit plugin-install action. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 3.23.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A postinstall hook changes the separately installed Codex agent environment during a global npm install. It executes a remotely fetched installer and installs a marketplace plugin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-13T13:51:50.643Z - **Finished:** 2026-09-13T13:52:40.101Z - **Download time:** 1009 ms - **Static scan time:** 620 ms - **AI review time:** 47828 ms - **Total time:** 49458 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A postinstall hook changes the separately installed Codex agent environment during a global npm install. It executes a remotely fetched installer and installs a marketplace plugin. - **Trigger:** npm install -g @essentialai/cogent-bridge - **Impact:** A package installation can modify the user's Codex installation and extend its agent control surface without an explicit plugin-install action. - **Evidence paths:** package.json, scripts/postinstall-global.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T13:52:40.101Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic remote shell execution and Codex plugin installation - **Attack narrative:** Installing this package globally automatically invokes its postinstall hook. The hook fetches and pipes the Codex installer to a shell, then adds a Git marketplace and installs a Cogent plugin into Codex. These actions modify a foreign AI-agent control surface without a separate confirmation at lifecycle time. - **Rationale:** The guarded global-install condition does not provide explicit consent for an npm lifecycle hook to install remote software and alter Codex plugin configuration. This is concrete install-hook abuse affecting a foreign AI-agent control surface. - **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:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically., On global installation, that script downloads and executes a remote shell installer for Codex., The same install hook adds a marketplace and installs a Cogent plugin into Codex without a separate user confirmation. - **Evidence against:** The hook skips non-global installs, CI, and Windows., The runtime wrapper asks before its own fallback managed-Codex installation., No credential harvesting or exfiltration was found in the inspected install hook. ## Affected versions and remediation This report applies to @essentialai/cogent-bridge@3.23.3. - Avoid installing @essentialai/cogent-bridge@3.23.3. 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.
