Changes future agent behavior and relaxes Codex network restrictions across unrelated sessions. - **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:** 1.1.48 - **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. Global npm installation automatically modifies multiple foreign AI-agent instruction surfaces and enables Codex network access. The installed instructions introduce a remote authoritative reference. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-03T23:11:57.057Z - **Finished:** 2026-10-03T23:13:11.487Z - **Download time:** 1025 ms - **Static scan time:** 819 ms - **AI review time:** 72584 ms - **Total time:** 74430 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:** Global npm installation automatically modifies multiple foreign AI-agent instruction surfaces and enables Codex network access. The installed instructions introduce a remote authoritative reference. - **Trigger:** Global npm installation with lifecycle scripts enabled. - **Impact:** Changes future agent behavior and relaxes Codex network restrictions across unrelated sessions. - **Evidence paths:** package.json, scripts/postinstall.js, lib/install.js, lib/targets.js, lib/codex-config.js, lib/persona.js, persona.md - **Review source:** ai\_review - **Reviewed:** 2026-10-03T23:13:11.487Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook invokes global setup, which selects default agent destinations, writes persona instructions, and changes Codex configuration without a consent prompt. - **Attack narrative:** During global installation, npm runs the postinstall hook. It calls global setup without prompting, writes package personas into several AI clients' global instructions, and enables Codex network access even when an existing setting disables it. The persona directs future relevant sessions to fetch and follow a remote reference. Backups and the local-install guard limit the scope but do not provide consent for these global control-surface changes. - **Rationale:** Inspected source establishes unconsented postinstall mutation of broad, foreign AI-agent control surfaces, which meets the supplied blocking policy. The decision does not rely on scanner similarity labels or inferred credential theft. - **Files touched:** ~/.claude/CLAUDE.md, ~/.agents/AGENTS.md, ~/.codex/AGENTS.md, ~/.codex/config.toml, ~/.gemini/GEMINI.md - **Network endpoints:** https://raw.githubusercontent.com/babylontoolkit/agent/main/reference.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically invokes global setup during global installation without a consent prompt., Global setup applies Codex configuration and agent personas automatically., Default targets include the global Codex instruction file and configuration, alongside other AI clients., Codex configuration merging changes an existing network-access setting to true., Persona installation prepends package instructions to existing agent instruction files., The installed persona requires fetching a remote reference before relevant work and treating it as authoritative. - **Evidence against:** Local npm installation skips automatic setup., Instruction-file changes preserve existing content and create backups. ## Affected versions and remediation This report applies to @babylonjs-toolkit/agent@1.1.48. - Avoid installing @babylonjs-toolkit/agent@1.1.48. 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.
