Subsequent AI-agent sessions can automatically execute package-supplied hooks and MCP servers. - **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:** 1.16.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm install automatically alters multiple unrelated AI-agent user configurations. It installs hooks, MCP servers, instructions, and a trusted Grok plugin pointing to DevCodex runtime code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-11T00:54:39.240Z - **Finished:** 2026-08-11T00:55:19.506Z - **Download time:** 501 ms - **Static scan time:** 9042 ms - **AI review time:** 30721 ms - **Total time:** 40266 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically alters multiple unrelated AI-agent user configurations. It installs hooks, MCP servers, instructions, and a trusted Grok plugin pointing to DevCodex runtime code. - **Trigger:** npm global install/update, causing postinstall - **Impact:** Subsequent AI-agent sessions can automatically execute package-supplied hooks and MCP servers. - **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, scripts/lib/host-adapter-scope.js, scripts/lib/global-host-config-transaction.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T00:55:19.506Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven multi-host AI-agent configuration and plugin mutation - **Attack narrative:** On a global installation, the postinstall hook calls applyGlobalHostConfig for Copilot, Claude, Codex, Gemini, and Grok. The configuration plan writes user-level hooks, instructions, and MCP entries that execute DevCodex runtime scripts; it also calls the Grok CLI to install/update a local plugin with --trust. These are broad foreign AI-agent control surfaces modified automatically during npm lifecycle execution. - **Rationale:** Source inspection confirms unconsented postinstall mutation of broad, foreign AI-agent control surfaces, meeting the blocking policy. Guardrails around filesystem boundaries do not remove that control-surface impact. - **Files touched:** $HOME/.copilot, $HOME/.claude, $HOME/.codex, $HOME/.gemini, $HOME/.grok, $HOME/.agents, VS Code User/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., postinstall executes global host configuration on global installs., Targets Copilot, Claude, Codex, Gemini, and Grok user config roots., Writes global hooks and MCP server entries that execute package runtime code., Also invokes \`grok plugin install \ --trust\` during postinstall. - **Evidence against:** Workspace installs and CI are normally skipped., Writes use path-bound transactions and preserve some existing config., No credential harvesting or network exfiltration found in inspected paths. ## Public findings ### 1.
