## Summary

Togoder Security scanned the npm package acorn@8.18.0 on Oct 6, 2026. An AI review of 1 source file produced 1 low severity finding. No malicious behavior, install-time payloads, credential theft or exfiltration were identified.

## Findings

### [low] File system read

Finding ID: `NPS-EE2585055525`

File: `dist/bin.js:68`

The script reads files specified as command-line arguments and from stdin. This is expected behavior for a CLI parser/validator tool (acorn) and operates only on user-provided paths outside the package scope in a legitimate, non-malicious manner.

## Files reviewed

- `dist/bin.js` (safe): The code is a legitimate CLI wrapper for the acorn JavaScript parser that reads user-specified files/stdin and prints parsed output; no malicious patterns such as exfiltration, credential harvesting, obfuscation, shell execution, or dynamic code evaluation were detected.
