Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection shows a postinstall hook gated on global installation that sets up this package's CLI launcher. The inspected entrypoint selects and launches the platform binary; no malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-12T05:23:53.357Z - **Finished:** 2026-10-12T05:24:27.059Z - **Download time:** 4295 ms - **Static scan time:** 32 ms - **AI review time:** 29374 ms - **Total time:** 33702 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:** No malicious attack surface was identified in the inspected files. The postinstall hook conditionally sets up the package's global launcher, and the CLI launches its platform binary. - **Trigger:** The postinstall hook runs during installation and exits unless npm indicates a global install; the launcher then runs when the user invokes the codex command. - **Impact:** Global installation changes the codex launcher in the global prefix; no broader attack impact was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T05:24:27.059Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** For a global install, the hook replaces the codex launcher under the configured prefix with a link or wrapper to this package. The CLI resolves a platform-specific binary and spawns it with the user's arguments. - **Rationale:** Source inspection shows a postinstall hook gated on global installation that sets up this package's CLI launcher. The inspected entrypoint selects and launches the platform binary; no malicious behavior was established. - **Files touched:** package.json, scripts/postinstall.mjs, bin/codex.js ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs only for global installs; local installs exit immediately., The global installer replaces the package's own codex launcher in the configured global prefix with a link or wrapper to this package., The CLI selects a platform-specific Codex binary and launches it with the caller's arguments and inherited environment. - **Evidence against:** The inspected launcher setup is limited to global installation and does not create an AI-agent control surface., The CLI entrypoint delegates to a platform package binary; no malicious behavior was identified in the inspected source. ## Affected versions and remediation This report applies to @codexed/codex@0.156.1-codexed.1. - Review the evidence and your use of @codexed/codex@0.156.1-codexed.1 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.

Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.mjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.mjs ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4.
