Subsequent Codex invocations execute package-supplied 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:** 0.153.4-patch.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. On global npm installation, a postinstall hook replaces executables in the separate @openai Codex package with bundled native binaries. This is an unconsented lifecycle mutation of a foreign AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-12T21:51:11.670Z - **Finished:** 2026-09-12T21:52:03.638Z - **Download time:** 2805 ms - **Static scan time:** 180 ms - **AI review time:** 48982 ms - **Total time:** 51968 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:** On global npm installation, a postinstall hook replaces executables in the separate @openai Codex package with bundled native binaries. This is an unconsented lifecycle mutation of a foreign AI-agent control surface. - **Trigger:** npm install -g of this package with lifecycle scripts enabled on Windows x64 - **Impact:** Subsequent Codex invocations execute package-supplied binaries instead of the installed @openai binaries. - **Evidence paths:** package.json, bin/powershell.js, install.ps1 - **Review source:** ai\_review - **Reviewed:** 2026-09-12T21:52:03.638Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall PowerShell overwrite of foreign Codex executables - **Attack narrative:** Installing the package globally automatically invokes a PowerShell installer. It discovers the global @openai Codex platform package, backs up its executables, and overwrites them with the package's bundled codex.exe and apply\_patch.exe. The replacement occurs during npm lifecycle processing rather than through a separate user-invoked setup command. - **Rationale:** The lifecycle hook automatically replaces a foreign AI-agent executable with opaque bundled binaries. Backups and hash checks do not remove the install-time control-surface takeover. - **Files touched:** @openai/codex-win32-x64/vendor/x86\_64-pc-windows-msvc/bin/codex.exe, @openai/codex-win32-x64/vendor/x86\_64-pc-windows-msvc/codex-path/apply\_patch.exe, codex.exe, apply\_patch.exe, install.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** An automatic postinstall runs the installer., The lifecycle wrapper launches PowerShell with execution-policy bypass., The installer locates the separate global @openai Codex package and selects its executables., It backs up and then replaces the foreign Codex and apply\_patch executables with bundled binaries. - **Evidence against:** The source limits execution to global installs on Windows x64., The installer verifies its bundled hashes and creates backups., No network, credential collection, or exfiltration code was found in the inspected text sources. ## Affected versions and remediation This report applies to @chenronggui/codex-win-patch@0.153.4-patch.3. - Avoid installing @chenronggui/codex-win-patch@0.153.4-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. ## Public findings ### 1.
