Future sessions in multiple AI coding tools can invoke package-controlled hooks and MCP runtimes without a separate setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.17.11 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm postinstall automatically modifies user-level control surfaces for Copilot, Claude, Codex, Gemini, Grok, and Cursor. It installs instructions, hooks, plugins, and MCP configuration that execute package-controlled runtime content in later agent sessions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-21T23:59:23.797Z - **Finished:** 2026-08-22T00:00:45.583Z - **Download time:** 501 ms - **Static scan time:** 11149 ms - **AI review time:** 70135 ms - **Total time:** 81786 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm postinstall automatically modifies user-level control surfaces for Copilot, Claude, Codex, Gemini, Grok, and Cursor. It installs instructions, hooks, plugins, and MCP configuration that execute package-controlled runtime content in later agent sessions. - **Trigger:** npm install -g devcodex - **Impact:** Future sessions in multiple AI coding tools can invoke package-controlled hooks and MCP runtimes without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T00:00:45.583Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall global multi-host AI-agent hook and MCP registration - **Attack narrative:** Installing globally invokes postinstall, which calls the global-host configuration writer. That writer targets six AI-agent products and registers package-controlled instructions, hooks, MCP configurations, and plugins under their user-level homes. Those registrations can execute on later prompt and tool events, creating an unconsented broad foreign-agent control surface. - **Rationale:** This is a concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, meeting the firewall block boundary despite the lack of observed exfiltration. - **Files touched:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js, ~/.copilot, ~/.claude, ~/.codex, ~/.gemini, ~/.grok, ~/.cursor ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Manifest runs a postinstall script., Postinstall executes global host configuration on global npm install., It targets six unrelated AI-agent host homes., It writes global hooks, instructions, plugins, and MCP configuration. - **Evidence against:** Workspace installs are skipped and instruct users to use a global install., No executable network client or credential-exfiltration path was found in inspected runtime sources. ## Public findings ### 1.
