Existing agent status-line commands can be displaced without user consent, causing Claude Code to execute the installed renderer on subsequent status updates. - **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:** 2.0.0 - **Selected version is latest:** Yes - **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. Automatic npm installation replaces Claude Code command registrations in global agent settings. The postinstall caller bypasses the installer's overwrite prompts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-30T15:43:03.150Z - **Finished:** 2026-09-30T15:45:07.353Z - **Download time:** 752 ms - **Static scan time:** 143 ms - **AI review time:** 123307 ms - **Total time:** 124203 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:** Automatic npm installation replaces Claude Code command registrations in global agent settings. The postinstall caller bypasses the installer's overwrite prompts. - **Trigger:** npm installation with lifecycle scripts enabled. - **Impact:** Existing agent status-line commands can be displaced without user consent, causing Claude Code to execute the installed renderer on subsequent status updates. - **Evidence paths:** package.json, scripts/postinstall.js, statusline.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T15:45:07.353Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script passes --install --yes; the installer accepts replacement prompts and persists package commands in settings.json. - **Attack narrative:** During npm installation, the postinstall script launches the status-line installer with automatic confirmation enabled. The installer copies its renderer into the user's .claude directory and replaces existing status-line command registrations in global Claude Code settings. Although the renderer serves the package's advertised purpose, the lifecycle caller removes the consent barrier for modifying another agent's control surface. - **Rationale:** Source proves unconsented npm lifecycle mutation of global Claude Code command settings, including replacement of existing commands. This meets the supplied blocking rule independently of credential theft or remote payload execution. - **Files touched:** .claude/settings.json, .claude/statusline.js, .claude/pricing.json, .claude/loopctl.js, .claude/loop-state.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs install and postinstall scripts during npm installation., scripts/postinstall.js invokes the installer with --yes, bypassing user confirmation., statusline.js automatically accepts overwrite prompts when --yes is present., The installer replaces existing statusLine and subagentStatusLine commands and writes the user's global Claude Code settings.json., The configuration destination is the user's .claude directory, outside the installed package. - **Evidence against:** The registered commands run the package's status renderer, consistent with its stated functionality., Legacy hook cleanup targets commands referencing loopctl.js., The pricing updater fetches JSON pricing data; no credential forwarding was established. ## Affected versions and remediation This report applies to @tangjianfang/claudecode-statusline@2.0.0. - Avoid installing @tangjianfang/claudecode-statusline@2.0.0. 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.
