## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 3.25.5
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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. Global installation automatically provisions a first-party Codex extension and may execute the official Codex installer. This establishes an extension lifecycle risk, but no confirmed malicious attack.

## Latest scan

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:** Global installation automatically provisions a first-party Codex extension and may execute the official Codex installer. This establishes an extension lifecycle risk, but no confirmed malicious attack.

- **Trigger:** npm global installation, or installation with COGENT\_FORCE\_SETUP=1, unless COGENT\_SKIP\_SETUP=1.

- **Impact:** Installation can add managed agent software and enable Cogent tools without a separate interactive prompt. The inspected code does not establish automatic future plugin updates or credential theft.

- **Evidence paths:** package.json, scripts/postinstall-global.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-01T13:36:43.263Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The postinstall hook invokes shell installation when needed, then runs Codex marketplace and plugin installation commands.

- **Rationale:** Source proves automatic first-party agent extension setup during global installation, which the supplied policy classifies as warning-worthy. No independently supported block-eligible attack was established.

- **Network endpoints:** https://chatgpt.com/codex/install.sh, https://github.com/eaisdevelopment/cogent.git

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 95.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json automatically runs scripts/postinstall-global.mjs after installation., Setup normally requires a global install; skip, force, CI, and platform checks control activation., When the managed Codex build is absent, the hook executes the official remote installer through a shell., The hook registers the vendor's marketplace and installs cogent@cogent without an interactive consent prompt., The explicit cogent-codex command separately requests confirmation before installing a missing managed build.

- **Evidence against:** The installed plugin belongs to the package's vendor, supporting a first-party extension warning rather than a control-hijack block., The inspected scaffolding callers ask users to choose setup mode and project locations., No credential export or broad agent instruction mutation was established in the inspected install hook.

## Affected versions and remediation

This report applies to @essentialai/cogent-bridge@3.25.5.

- Review the evidence and your use of @essentialai/cogent-bridge@3.25.5 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.
