## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Subsequent agent sessions receive package-authored instructions and expanded Codex network permissions.

- **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:** 1.1.46
- **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 changes foreign AI-agent instruction files and Codex sandbox configuration without separate consent.

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 changes foreign AI-agent instruction files and Codex sandbox configuration without separate consent.

- **Trigger:** Global npm installation with lifecycle scripts enabled.

- **Impact:** Subsequent agent sessions receive package-authored instructions and expanded Codex network permissions.

- **Evidence paths:** package.json, scripts/postinstall.js, lib/install.js, lib/targets.js, lib/paths.js, lib/codex-config.js, .codex/config.toml, lib/persona.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-01T18:34:26.986Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The postinstall hook invokes the installer, which resolves home-directory agent targets, prepends persona instructions, and writes configuration enabling network access.

- **Attack narrative:** The global npm postinstall hook runs setup without prompting. Setup selects multiple foreign agent control files by default, adds package persona instructions, and enables Codex workspace network access. The global-install guard and backups limit exposure but do not provide consent for these broad control-surface changes.

- **Rationale:** Inspected source establishes unconsented postinstall mutation of broad, foreign AI-agent control surfaces, meeting the blocking policy. This conclusion rests on executable lifecycle behavior, not citation capacity or inferred credential theft.

- **Files touched:** ~/.claude/CLAUDE.md, ~/.agents/AGENTS.md, ~/.codex/AGENTS.md, ~/.gemini/GEMINI.md, ~/.codex/config.toml

### 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 for global installations, without a consent prompt., Default targets include shared agent instructions and Codex configuration in the user's home directory., The installer applies Codex configuration changes automatically., The configuration writer creates or updates the selected file with network access enabled., The shipped Codex template enables workspace sandbox network access., The persona writer prepends package instructions to existing agent instruction files.

- **Evidence against:** Local dependency installations skip automatic setup., Modified configuration and instruction files receive backups.

## Affected versions and remediation

This report applies to @babylonjs-toolkit/agent@1.1.46.

- Avoid installing @babylonjs-toolkit/agent@1.1.46. 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.
