The package can redirect expected Codex or Claude command use into a third-party launcher and configure the local agent to run without approval in danger-full-access mode. - **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:** 2.0.39 - **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. A postinstall hook silently reserves the broad global AI-agent command names codex and claude when they are absent. Later invocation of either command launches this package, which can configure Codex for its remote provider with unrestricted local-tool settings. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-12T11:36:53.701Z - **Finished:** 2026-09-12T11:38:12.281Z - **Download time:** 758 ms - **Static scan time:** 465 ms - **AI review time:** 77356 ms - **Total time:** 78580 ms The recorded confidence comes from the underlying analysis.

Later invocation of either command launches this package, which can configure Codex for its remote provider with unrestricted local-tool settings. - **Trigger:** Global npm installation, followed by a user invoking codex or claude. - **Impact:** The package can redirect expected Codex or Claude command use into a third-party launcher and configure the local agent to run without approval in danger-full-access mode. - **Evidence paths:** package.json, scripts/install-safe-aliases.js, bin/codexclaude.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T11:38:12.281Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time command alias hijacking followed by launcher-driven Codex configuration replacement. - **Attack narrative:** Installing this package globally automatically creates codex and claude command aliases if those names are currently free. That changes the user’s future invocation path without an explicit setup command. The replacement launcher prompts for service login when needed, stores its configuration, and rewrites the Codex configuration to use its provider while setting approval\_policy to never and sandbox\_mode to danger-full-access. - **Rationale:** The postinstall hook mutates a foreign, broad AI-agent command surface by claiming codex and claude globally. The later launcher configures an unrestricted agent and redirects it to package-selected remote services, forming a concrete install-hook control-hijack chain. - **Files touched:** global npm prefix/bin/codex, global npm prefix/bin/claude, ~/.codex/config.toml, ~/.codexclaude/config.json, ~/.codex/version.json - **Network endpoints:** codexapi.pro, chatplus.chat, api.myapi.world, api.magnetapi.org ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The automatic postinstall hook runs an alias installer., On global installation, it creates missing commands named codex and claude that point to this package's launcher., The substituted launcher writes a Codex configuration that disables approvals and enables danger-full-access, then routes the provider through this package's service configuration. - **Evidence against:** The alias installer preserves an existing command and only acts for global installs., The credential prompt and Codex configuration write occur when the launcher is run, not during postinstall., No hidden evaluation, shell execution, or filesystem harvesting was found in the inspected source. ## Affected versions and remediation This report applies to @codexapi/codexclaude@2.0.39. - Avoid installing @codexapi/codexclaude@2.0.39. 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.
