Multi-agent orchestration layer for OpenAI Codex CLI
AI Security Review
scanned 13d ago · by lpm-firewall-aiSource inspection found no concrete attack behavior, but global postinstall can acquire a native executable automatically, so residual lifecycle risk remains. Agent configuration locations inspected were test fixtures or read-only discovery, not install-time mutation.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package globally through npm on a supported platform, unless native auto-fetch is disabled or the runtime is already cached.
Impact
A package-selected native executable is acquired during global installation; the inspected source does not establish malicious payload behavior.
Mechanism
The postinstall path requests a release manifest, downloads a selected native archive, checks its size and SHA-256, then extracts and caches its binary.
AI rationale
Source inspection found no concrete attack behavior, but global postinstall can acquire a native executable automatically, so residual lifecycle risk remains. Agent configuration locations inspected were test fixtures or read-only discovery, not install-time mutation.
Evidence
dist/scripts/postinstall.jsdist/cli/native-assets.js
Decision evidence
public snapshotAI called this Suspicious at 73.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook runs only for global installs; local installs return without work.
- A global install automatically hydrates a native runtime from release assets, creating a lifecycle-time executable acquisition path.
- The downloaded archive is checked against the release manifest’s size and SHA-256 before extraction and caching.
- Native agent files are generated under user or project Codex directories, while agent management is exposed through explicit CLI commands.
- The inspected agent configuration target locations are test fixtures or read-only configuration discovery.
Evidence against
- The source inspected here does not establish credential collection, unrelated data transfer, consumer policy changes, or unconsented agent configuration mutation.
