Subsequent Codex and apply\_patch executions run package-supplied binaries instead of the original installed files. - **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.2 - **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. Global npm installation automatically replaces executables inside an existing @openai Codex installation. This mutates a foreign AI-agent command surface with opaque bundled binaries. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-20T01:48:49.287Z - **Finished:** 2026-09-20T01:49:42.984Z - **Download time:** 2786 ms - **Static scan time:** 194 ms - **AI review time:** 50716 ms - **Total time:** 53697 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:** Global npm installation automatically replaces executables inside an existing @openai Codex installation. This mutates a foreign AI-agent command surface with opaque bundled binaries. - **Trigger:** npm install -g invokes postinstall. - **Impact:** Subsequent Codex and apply\_patch executions run package-supplied binaries instead of the original installed files. - **Evidence paths:** package.json, bin/install.js, install.ps1 - **Review source:** ai\_review - **Reviewed:** 2026-09-20T01:49:42.984Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** PowerShell copies bundled executables over @openai Codex binaries. - **Attack narrative:** Installing this package globally triggers its postinstall launcher. The launcher runs install.ps1, which searches the global npm tree for @openai Codex and copies the package's bundled codex.exe and apply\_patch.exe over the trusted installation. Backups do not make the automatic replacement consented or constrain what the replacement binaries can do. - **Rationale:** This is an unconsented postinstall mutation of a foreign AI-agent executable surface. The package transparently performs the replacement, but it supplies opaque native payloads that take over later Codex execution. - **Files touched:** @openai/codex/vendor/x86\_64-pc-windows-msvc/bin/codex.exe, @openai/codex/vendor/x86\_64-pc-windows-msvc/codex-path/apply\_patch.exe, codex.exe, apply\_patch.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The install lifecycle automatically runs the installer., The Node launcher accepts the postinstall invocation and runs PowerShell., The installer locates the separately installed @openai Codex platform package., The installer replaces that package's codex.exe and apply\_patch.exe with bundled executables. - **Evidence against:** The script creates backups and includes a separate restore command., No package-source network request or credential collection was found in the inspected launchers and PowerShell scripts. ## Affected versions and remediation This report applies to @chenronggui/codex-win-patch@0.155.1-patch.2. - Avoid installing @chenronggui/codex-win-patch@0.155.1-patch.2. 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.
