AI Security Review

scanned 2d ago · by lpm-firewall-ai

Inspected source shows CLI and Claude history functionality, but no concrete attack behavior. Some declared dependency source remained unresolved, so the package cannot be cleared as clean from this review.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

The package's CLI entry point starts the command-line application.

Impact

No confirmed attack impact was identified. Unreviewed dependency behavior prevents a clean determination.

Mechanism

The inspected worker handles Claude session history operations and returns results to its caller; the reviewed excerpts do not show an unrelated recipient or covert transfer.

AI rationale

Evidence

package.jsondist/binCli-CTh3xknE.mjsdist/claudeHistoryWorker-js6Jgg9C.mjsdist/claude-history-worker.mjs

Decision evidence

public snapshot

AI called this Manual Review at 76.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies a CLI entry point and declares dependencies, with no lifecycle script in the inspected manifest.
The Claude history worker accepts two named operations, requires a session ID, and writes the result to standard output.
The CLI loads the Cursor SDK and Playwright for product features.
The manifest declares dependencies whose complete source was not available for this review.
