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. The install-time replacement of a global codex launcher presents a real command-displacement risk, so this warrants a warning. The inspected source does not establish broader control-surface hijacking or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-12T05:25:35.464Z - **Finished:** 2026-10-12T05:25:56.190Z - **Download time:** 772 ms - **Static scan time:** 33 ms - **AI review time:** 19920 ms - **Total time:** 20726 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 global installation replaces the existing codex launcher in the configured package-manager prefix. This is a command replacement with a narrow target, but the hook does not preserve or verify the launcher it removes. - **Trigger:** Installing the package globally through npm or another compatible installer. - **Impact:** A pre-existing codex command at that location is displaced and subsequent invocations run this package’s CLI. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T05:25:56.190Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook removes the prefix’s codex launcher and installs a symlink to this package’s launcher; Windows installs write codex command shims. - **Rationale:** The install-time replacement of a global codex launcher presents a real command-displacement risk, so this warrants a warning. The inspected source does not establish broader control-surface hijacking or other concrete malicious behavior. - **Files touched:** package.json, scripts/postinstall.mjs, bin/codex.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall hook that calls scripts/postinstall.mjs., On global installs, the hook removes the existing codex launcher under the configured prefix and replaces it with a symlink to this package., The launcher forwards CLI arguments to the package’s platform binary. - **Evidence against:** The launcher replacement is gated on a global-install setting; local installs exit without modifying the launcher., The inspected launcher code starts the bundled platform executable and inherits the user’s environment. ## Affected versions and remediation This report applies to @codexed/codex@0.160.0-codexed.4. - Review the evidence and your use of @codexed/codex@0.160.0-codexed.4 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.
