## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Future Codex use runs package-supplied native binaries instead of the installed @openai binaries.

- **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:** 0.155.1-patch.3
- **Selected version is latest:** Yes
- **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. An npm postinstall hook replaces executables in the separately installed @openai Codex package with opaque binaries shipped by this package. This is an unconsented mutation of a foreign AI-agent control surface.

## Security analysis

### Published attack-surface review

- **Summary:** An npm postinstall hook replaces executables in the separately installed @openai Codex package with opaque binaries shipped by this package. This is an unconsented mutation of a foreign AI-agent control surface.

- **Trigger:** Installing this package globally invokes its postinstall hook.

- **Impact:** Future Codex use runs package-supplied native binaries instead of the installed @openai binaries.

- **Evidence paths:** package.json, bin/powershell.js, install.ps1

- **Review source:** ai\_review

- **Reviewed:** 2026-09-20T03:30:47.197Z

### AI review details

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

- **Mechanism:** Node launches PowerShell, which finds the global Codex package and copies this package's codex.exe and apply\_patch.exe over its executable paths.

- **Attack narrative:** A global npm installation automatically launches the package installer. The installer targets a separately installed @openai Codex directory and overwrites its executable and helper binary with opaque package payloads. Backups and checksum checks do not remove the risk because the substituted payload is still selected and installed by this package.

- **Rationale:** The automatic postinstall chain mutates another vendor's Codex executable paths with opaque native binaries. This meets the install-control-surface blocking boundary despite its backup and verification logic.

- **Files touched:** package.json, bin/install.js, bin/powershell.js, install.ps1

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** The package automatically runs an installer after npm installation., The installer invokes PowerShell and passes the package install script., The PowerShell script locates the separately installed @openai Codex package and replaces its codex.exe and apply\_patch.exe binaries.

- **Evidence against:** The script verifies packaged binary hashes, saves backups, and restores them if installation fails., No source-visible network request, credential collection, or data export was found.

## Affected versions and remediation

This report applies to @chenronggui/codex-win-patch@0.155.1-patch.3.

- Avoid installing @chenronggui/codex-win-patch@0.155.1-patch.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.
