Later invocations of either newly created command run this package's launcher instead of requiring the user to invoke codexclaude explicitly. - **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:** 2.0.40 - **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. An npm postinstall hook can claim unoccupied global codex and claude command names for this package. This is an unconsented mutation of a broad AI-agent command surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-22T12:56:10.524Z - **Finished:** 2026-09-22T13:05:06.557Z - **Download time:** 508 ms - **Static scan time:** 376 ms - **AI review time:** 535148 ms - **Total time:** 536033 ms The recorded confidence comes from the underlying analysis.

This is an unconsented mutation of a broad AI-agent command surface. - **Trigger:** Installing the package globally through npm activates postinstall. - **Impact:** Later invocations of either newly created command run this package's launcher instead of requiring the user to invoke codexclaude explicitly. - **Evidence paths:** package.json, scripts/install-safe-aliases.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T13:05:06.557Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script checks for global installation, then symlinks its launcher into the global bin directory under codex and claude when those names are absent. - **Attack narrative:** A global npm installation automatically runs an installer that creates aliases named codex and claude if those commands are not already found. The aliases point to this package's launcher. Although existing commands are preserved and an opt-out exists, the mutation occurs before the user has expressly chosen these foreign command names. - **Rationale:** The automatic postinstall hook modifies unoccupied global AI-agent command names, creating a concrete command-control hijack surface. Its guards reduce scope but do not provide prior consent for that lifecycle mutation. ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs an alias installer automatically in postinstall., The installer targets the foreign AI command names codex and claude., On global installs, it creates a symlink from an unoccupied command path to this package's launcher., The installer executes when invoked as the lifecycle script. - **Evidence against:** The installer skips non-global installs and can be disabled with an environment flag., It preserves an existing command rather than overwriting it. ## Affected versions and remediation This report applies to @codexapi/codexclaude@2.0.40. - Avoid installing @codexapi/codexclaude@2.0.40. 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.
