AI Security Review

scanned 9d ago · by lpm-firewall-ai

Source inspection found a narrowly gated runtime migration in the global postinstall path and product-aligned runtime behavior. The flagged agent paths resolve to project/session data, while persistent service setup is presented as an explicit CLI action.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A global npm install invokes the postinstall hook; the bridge proceeds only when its adoption and version checks pass.

Impact

No unconsented foreign agent configuration change, credential theft, or other concrete attack effect was established.

Mechanism

It stages a product runtime update and updates the version pointer. The inspected agent integration paths access project history, memory, and session data; service setup is offered as an explicit CLI command.

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest’s postinstall invokes the bridge, while the hook runs it only for global npm installs.
The bridge skips unless an existing version store is adopted and complete and the installed version is newer; it prepares a runtime migration for that store.
The indicated Claude and Codex locations resolve to project history, project memory, and session directories, not global agent settings or plugin locations.
The inspected runtime hints cover executable path lookup, work-directory file upload, Git status parsing, and local backend text or attachment handling.
The service code selects user-level service artifact locations, and the CLI presents service installation as an explicit command.
The configured relay defaults to the product service, and the connection sends a configured password as relay authentication.
