Lystech Core contains essentials for lystech apps

AI Security Review

scanned 13d ago · by lpm-firewall-ai

The automatic postinstall mutation adds consumer CI automation and sends repository metadata to the package service, creating a real but unresolved install-time risk. The inspected behavior does not establish a concrete attack or unrelated credential exfiltration, so this warrants a warning rather than a publish block.

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 depends on @lystech/core and lacks the workflow, unless SKIP_LYSTECH_SETUP is true.

Impact

This silently adds CI automation to the consumer project and shares repository metadata with the package service. Inspected source does not show consumer credentials being sent to an unrelated host.

Mechanism

The postinstall script creates .github/workflows/sync-package-registry.yml; the workflow uses GITHUB_TOKEN with GitHub and posts repository metadata to the registry endpoint.

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs bin/postinstall.cjs automatically on install.
The postinstall hook can create a workflow in the consumer repository without an explicit setup command; it skips creation only when disabled, when the package is absent from dependencies, or when the workflow already exists.
The generated workflow uses the repository's GitHub token to query GitHub, then sends repository identifiers to the package registry endpoint.
The bundle's stored auth values are attached to a client with a fixed api.lystech.ca base URL.

Evidence against

The postinstall hook has skip conditions and preserves an existing workflow.
The inspected bundle sends its stored credentials to the package's fixed API host, with no evidence here of forwarding them to an unrelated recipient.
