@lystech/core@3.0.107

Lystech Core contains essentials for lystech apps

AI Security Review

scanned 13d ago · by lpm-firewall-ai

The automatic install hook creates a consumer repository workflow that can change registry state, so the package presents a concrete unresolved install-time mutation risk. The inspected evidence does not meet the supplied criteria for blocking malicious behavior.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installing the package when the consumer project declares @lystech/core, unless SKIP_LYSTECH_SETUP=true is set.

Impact

A new workflow may run on later pushes or manual dispatch and change registry state for the project.

Mechanism

The hook writes .github/workflows/sync-package-registry.yml containing registry synchronization actions.

AI rationale

Evidence

package.jsonbin/postinstall.cjs.github/workflows/sync-package-registry.yml

Network endpoints1

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package runs bin/postinstall.cjs automatically after installation.
The install hook can create a GitHub Actions workflow in a consuming project when that project declares @lystech/core.
The hook has a SKIP_LYSTECH_SETUP=true guard, but otherwise writes the workflow automatically.
The workflow includes a request to the package registry endpoint to delete a package/repository entry.

Evidence against

The setup can be skipped through SKIP_LYSTECH_SETUP=true.
The inspected code did not establish credential collection, secret theft, or mutation of an AI-agent control surface.
