AI Security Review

scanned 5d ago · by lpm-firewall-ai

The manifest has no install lifecycle hook, and the flagged CLI behavior is tied to explicit project commands. The inspected source does not establish credential disclosure to an unrelated recipient or another concrete attack.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A user runs a CLI command such as project pull, publish, or setup.

Impact

No confirmed attack surface was established.

Mechanism

The CLI sends authenticated requests to the selected dashboard and performs the requested project operations; no automatic install-time trigger was found.

AI rationale

Decision evidence

public snapshot

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

Evidence for AI clean decision

package.json exposes a CLI and library exports, with no install lifecycle hook.
The CLI checks for a Pattern project before running project commands.
Pulling a project requires an explicit CLI command and a signed-in session.
Saved cookies are associated with the selected dashboard; publishing requests send them to that dashboard.
The cited runtime files implement state, UI, platform, database, authentication, and theme utilities.

Evidence against

Scanner labels mention download execution, command output, and dynamic loading, but inspected source shows project pull and setup flows rather than an automatic install-time trigger.
The inspected CLI setup code checks before replacing an existing global shim and refuses to overwrite an unrecognized file.
