Jait AI gateway — local-first AI coding agent with terminal, filesystem, and browser control

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic pip installation is a meaningful install-time supply-chain risk and warrants a warning. Source inspection did not establish concrete malicious payload behavior, self-dependency chaining, or credential exfiltration.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm installation, through the postinstall lifecycle hook.

Impact

A compromised or unsafe external Python distribution could execute during npm installation outside the npm dependency graph.

Mechanism

Automatic Python virtual-environment creation and pip package installation.

AI rationale

Evidence

package.jsonbin/install-runtime.mjsdist/services/code-graph/graphify-runtime.js~/.jait/runtime/graphify/venv~/.jait/runtime/graphify/runtime.json

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The npm postinstall hook runs a package script automatically.
That script imports a runtime provisioner during installation.
The provisioner creates a Python virtual environment and runs pip to install graphifyy version 0.9.30.

Evidence against

The dependency is explicitly version-pinned and the installation logic is readable, not obfuscated.
The manifest has no runtime dependency on its own package name.
The inspected web-search code sends configured API keys only to the selected search provider when that tool is invoked; it does not show separate credential harvesting.
