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

AI Security Review

scanned 7d ago · by lpm-firewall-ai

The postinstall hook performs an automatic third-party runtime installation, leaving a concrete lifecycle supply-chain risk that warrants a warning. The inspected behavior does not show credential theft, account manipulation, or other malicious activity.

Static reason

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

Trigger

Installing the npm package runs its postinstall hook.

Impact

Installation can execute code from the separately distributed Graphify package without a distinct confirmation prompt.

Mechanism

The hook imports the Graphify runtime provisioner, which creates a virtual environment and invokes pip to install a pinned Graphify release when one is not already ready.

AI rationale

Evidence

package.jsonbin/install-runtime.mjsdist/services/code-graph/graphify-runtime.js

Decision evidence

public snapshot

AI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package postinstall calls a runtime provisioner automatically during installation.
When the pinned Graphify runtime is absent, the provisioner creates a Python virtual environment and runs pip to install Graphify.
The gateway also starts this optional runtime on normal startup, supporting a product feature rather than a hidden install-only action.
The cited Git operations fetch or clone caller-selected repositories; they do not show automatic account changes.
The pi integration writes session-scoped MCP configuration instead of changing global or project configuration.
Browser search uses configured API keys for a validated provider endpoint; the inspected source does not show a transfer to an unrelated recipient.

Evidence against

The postinstall hook installs executable third-party Python package code without a separate user prompt.
The source pins the Graphify package version and places the managed runtime in Jait's state directory.
