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

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The source does not show credential theft or covert exfiltration, but its postinstall hook automatically downloads and installs an external Python runtime into the user home directory. This is an unresolved install-hook supply-chain risk and should be warned on.

Static reason

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

Trigger

npm installation invokes postinstall.

Impact

A registry install causes execution and persistence of a separate Python dependency outside node_modules.

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 Unknown with medium false-positive risk.

Evidence for warning

The package runs a postinstall hook automatically during npm installation.
The postinstall launcher imports and runs the Graphify runtime provisioner.
The provisioner creates a virtual environment under the user home directory and invokes pip to install an external Python package.

Evidence against

The Python package name and version are fixed in source rather than dynamically derived.
The installed runtime is used by the code-graph feature to extract a project graph.
The inspected web-search code uses API keys only in requests to selected service providers, not to an undisclosed collector.
