AI Security Review

scanned 6d ago · by lpm-firewall-ai

The inspected JavaScript supports CLI history operations and MCP configuration schemas without establishing an attack. The shipped native process-monitor executable is actively used but could not be analyzed, so its behavior remains unresolved.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

The CLI uses the monitor for terminal process telemetry.

Impact

The executable’s behavior and any effects beyond process monitoring could not be determined from the available analysis.

Mechanism

The source resolves a bundled executable and launches it as a subprocess with piped input and output.

AI rationale

Decision evidence

public snapshot

AI called this Manual Review at 83.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest exposes a CLI binary and its complete dependency object contains no lifecycle scripts.
The flagged worker location reads Claude configuration and project-name environment variables; the runtime location defines MCP settings identifiers.
The history worker requires a session ID and accepts only history retrieval or session forking; the CLI passes its method and session ID to it.
The CLI resolves and launches a resource-monitor executable for terminal process telemetry, but the available offline analysis cannot identify the binary format or behavior.

Evidence against

The bundled native resource-monitor executable is used by the CLI, and its behavior remains unresolved after offline analysis.
