AI Security Review

scanned 2d ago · by lpm-firewall-ai

Source inspection confirms automatic postinstall execution of a separately fetched Python package when the managed Graphify runtime is unavailable. The package is version-pinned and aligned with the Graphify feature, so this supports a warning about install-time execution rather than a malware block.

Static reason

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

Trigger

Installing the npm package when its managed Graphify runtime is missing or not ready.

Impact

Code from the separately fetched Python package runs during installation before Graphify is explicitly invoked.

Mechanism

The hook invokes the Graphify runtime manager, which creates a virtual environment and uses pip to install a fixed package version.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package postinstall hook automatically runs the runtime installer.
The installer calls the Graphify runtime setup function.
When the managed runtime is unavailable, setup creates a virtual environment and uses pip to install a fixed Graphify package version.
The inspected Git operations redact secrets or run Git subprocesses; they do not show an unrelated account action.
The node credential route requires authentication and issues a credential for the requested node.

Evidence against

The inspected source pins the Graphify package version and installs it in the gateway's managed runtime directory.
The source does not establish that the package-selected Python dependency is malicious or sends data to an unrelated recipient.
