Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. A guarded postinstall on global npm install can download OpenAI's Codex installer through curl-to-sh and register this package's own cogent Codex plugin. Local, npx, CI, and Windows installs skip that setup. Remaining file writes are from an interactive init wizard, not install. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-16T18:40:16.558Z - **Finished:** 2026-09-16T18:42:41.039Z - **Download time:** 251 ms - **Static scan time:** 693 ms - **AI review time:** 143536 ms - **Total time:** 144481 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 guarded postinstall on global npm install can download OpenAI's Codex installer through curl-to-sh and register this package's own cogent Codex plugin. Local, npx, CI, and Windows installs skip that setup. Remaining file writes are from an interactive init wizard, not install. - **Trigger:** npm install -g @essentialai/cogent-bridge when npm\_config\_global is true - **Impact:** Unattended global install can change the local Codex CLI by installing a managed build and the cogent plugin. Source does not show secret theft or a hidden payload. - **Evidence paths:** package.json, scripts/postinstall-global.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-16T18:42:41.039Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded postinstall first-party Codex plugin and managed-build setup - **Rationale:** Global install runs a guarded postinstall that can fetch OpenAI's Codex installer and add this package's own cogent plugin, which is first-party agent-extension setup rather than a stealth hijack of a foreign agent. There is no credential theft, obfuscation, or self-dependency install chain, so the risk is warn-level lifecycle behavior, not a publish block. - **Files touched:** scripts/postinstall-global.mjs, ~/.codex/packages/standalone/current/codex - **Network endpoints:** https://chatgpt.com/codex/install.sh, https://github.com/eaisdevelopment/cogent.git ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json postinstall always runs scripts/postinstall-global.mjs after npm install., On a global install the script pipes https://chatgpt.com/codex/install.sh into sh with no prompt., The same global postinstall adds a GitHub marketplace and runs codex plugin add cogent@cogent., A user-run wizard can write project .mcp.json and CLAUDE.md for the cogent MCP server. - **Evidence against:** The installer returns immediately unless npm\_config\_global is true, and it also skips CI, Windows, and COGENT\_SKIP\_SETUP=1., The Codex change is this package's own cogent@cogent plugin via the official plugin CLI, not a silent rewrite of foreign Claude or Cursor user settings., Hosts used in source (cogent.tools, app.cogent.tools, registry.npmjs.org, chatgpt.com, github.com/eaisdevelopment) match the stated MCP relay and Codex setup., No obfuscation, secret exfil, eval, or runtime self-dependency on this package name; MCP start and the init wizard run only when the user launches the CLI or server. ## Affected versions and remediation This report applies to @essentialai/cogent-bridge@3.24.1. - Review the evidence and your use of @essentialai/cogent-bridge@3.24.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
