Changes global Codex, Claude, Copilot, Gemini, Grok, and Cursor control surfaces without a separate setup command. - **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:** 1.19.1 - **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 installation automatically modifies multiple user-level AI-agent configuration surfaces. It installs managed runtime and hook configuration that can run on later agent events. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-19T14:40:43.199Z - **Finished:** 2026-09-19T14:42:46.346Z - **Download time:** 1012 ms - **Static scan time:** 12244 ms - **AI review time:** 109889 ms - **Total time:** 123147 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:** A global npm installation automatically modifies multiple user-level AI-agent configuration surfaces. It installs managed runtime and hook configuration that can run on later agent events. - **Trigger:** Running npm install -g devcodex activates postinstall. - **Impact:** Changes global Codex, Claude, Copilot, Gemini, Grok, and Cursor control surfaces without a separate setup command. - **Evidence paths:** package.json, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js, scripts/lib/global-host-config-transaction.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T14:42:46.346Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall applies generated host configuration and hook runtime across six agent homes. - **Attack narrative:** Installing this package globally runs its postinstall hook. That hook invokes a non-dry-run configuration routine, defaults to all six supported AI-agent hosts, and writes generated configuration and runtime files into their user-level directories. This is an automatic broad mutation of foreign AI-agent control surfaces, and the installed hook runtimes can execute during later agent activity. - **Rationale:** The source establishes a complete automatic lifecycle-to-global-agent-configuration write path. Although no network exfiltration was found, this broad postinstall control-surface mutation warrants blocking under the isolation policy. - **Files touched:** ~/.copilot, ~/.claude, ~/.codex, ~/.gemini, ~/.grok, ~/.cursor, ~/.agents ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs a postinstall script., On global installation, the lifecycle code selects execution rather than a no-op., The lifecycle invokes global host configuration with dry-run disabled., The configuration targets six AI-agent host directories under the user home, including Codex and Claude., The configuration plan defaults to every global host and writes its generated operations transactionally., The global-host target list names Copilot, Claude, Codex, Gemini, Grok, and Cursor., The transaction promotes a staged file to its destination and marks the operation installed. - **Evidence against:** No runtime self-dependency on devcodex was found in the manifest., The inspected lifecycle code does not contain a network send operation. ## Affected versions and remediation This report applies to devcodex@1.19.1. - Avoid installing devcodex@1.19.1. 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.
