AI Security Review

scanned 13d ago · by lpm-firewall-ai

Inspected source does not substantiate the scanner’s credential-redirection claim: the launcher configures its official service key, and a child-process guard removes secret variables. The postinstall hook targets pi UI dependencies for compatibility patches; no concrete malicious behavior was found.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Package installation runs the postinstall hook; CLI startup performs the other inspected actions.

Impact

The inspected behavior supports package setup and CLI operation; no confirmed attack surface was established.

Mechanism

The hook patches selected pi UI files, while the launcher uses its configured service endpoint and strips secret environment variables from child processes.

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

The postinstall hook runs a patch script that targets the package’s pi UI dependencies.
The launcher sets its official API key for service use and installs a guard that strips secret variables from child-process environments.
The search-tool download uses a configured base URL and limits archive size.
The update check fetches package metadata from the npm registry.
Startup settings and error handling show ordinary CLI configuration behavior.

Evidence against

No inspected source showed credential forwarding to an unrelated destination or confirmed attack behavior.
The postinstall patch targets pi UI dependencies, and the inspected code showed no broad consumer-project or agent-control-surface mutation.
