Future Claude Code sessions execute the installed package script through replaced global command registrations; selected Stop hooks are also removed. - **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 changes the user's global Claude Code command configuration without interactive consent. Existing status command registrations can be replaced. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-30T15:37:31.443Z - **Finished:** 2026-09-30T15:39:27.370Z - **Download time:** 768 ms - **Static scan time:** 145 ms - **AI review time:** 115013 ms - **Total time:** 115927 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 changes the user's global Claude Code command configuration without interactive consent. Existing status command registrations can be replaced. - **Trigger:** npm install runs the package's postinstall lifecycle hook. - **Impact:** Future Claude Code sessions execute the installed package script through replaced global command registrations; selected Stop hooks are also removed. - **Evidence paths:** package.json, scripts/postinstall.js, statusline.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T15:39:27.370Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall launches setup with --yes, automatically approves overwrite prompts, and persists statusLine and subagentStatusLine command settings in ~/.claude/settings.json. - **Attack narrative:** The automatic postinstall hook launches statusline.js with --install and --yes. Setup copies its script into the user's Claude configuration directory and replaces global status command registrations, saving settings.json. The supplied flag bypasses existing-command overwrite prompts. Postinstall additionally removes matching Stop hook registrations. This establishes unconsented install-time mutation of another product's global agent control surface, irrespective of the status display's legitimate purpose. - **Rationale:** The source proves automatic install-time mutation of global Claude Code command settings with consent prompts bypassed. This meets the supplied blocking policy for a foreign AI-agent control surface. - **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 executes scripts/postinstall.js after installation., The postinstall script invokes statusline.js setup with --install and --yes., The --yes option makes overwrite prompts resolve to approval without user input., Setup writes command registrations for both status displays into the user's global Claude Code settings.json., Postinstall also filters Stop hook registrations and saves the modified global settings. - **Evidence against:** The installed commands implement the package's status display functionality., The pricing updater fetches pricing data and writes a pricing cache; inspected code does not establish credential exfiltration. ## Affected versions and remediation This report applies to @tangjianfang/cc-statusline@2.0.0. - Avoid installing @tangjianfang/cc-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.
