It can change instructions, hooks, MCP settings, and plugin state for Codex, Claude, Copilot, Gemini, Grok, and Cursor. - **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:** 1.20.0 - **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 global npm install automatically modifies user-level configuration for multiple AI coding agents and installs a trusted Grok plugin. This is a broad AI-agent control-surface change. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-07T10:16:20.104Z - **Finished:** 2026-09-07T10:18:35.261Z - **Download time:** 756 ms - **Static scan time:** 16909 ms - **AI review time:** 117491 ms - **Total time:** 135157 ms The recorded confidence comes from the underlying analysis.

This is a broad AI-agent control-surface change. - **Trigger:** Installing devcodex globally through npm. - **Impact:** It can change instructions, hooks, MCP settings, and plugin state for Codex, Claude, Copilot, Gemini, Grok, and Cursor. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/host-adapter-scope.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T10:18:35.261Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall applies cross-host adapters and installs a trusted plugin. - **Attack narrative:** On global npm installation, postinstall calls the lifecycle adapter. That adapter executes a global host configuration operation rather than requiring an explicit setup command. The configuration code targets six AI-agent home directories and writes agent instructions, hooks, MCP settings, and configuration. It also invokes the Grok CLI to install the package plugin with trust enabled. This creates an unconsented, broad persistent control surface across unrelated agent applications. - **Rationale:** The automatic global lifecycle path mutates broad AI-agent configuration and enables a trusted plugin. The workspace guard does not mitigate the automatic global-install behavior. - **Files touched:** .copilot, .claude, .codex/AGENTS.md, .codex/hooks.json, .codex/config.toml, .gemini, .grok, .cursor ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically., Global installation activates a configuration-writing action., The action targets six separate AI-agent user configuration roots., The lifecycle invokes Grok plugin installation with trust enabled. - **Evidence against:** Workspace installs are skipped and told to use a global install., No runtime dependency on devcodex is declared., No network exfiltration endpoint was found in the inspected lifecycle path. ## Affected versions and remediation This report applies to devcodex@1.20.0. - Avoid installing devcodex@1.20.0. 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.
