## Summary

Togoder Security scanned the npm package esquery@1.7.0 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] Dynamic RegExp construction

Finding ID: `NPS-A4CC0A2869C4`

File: `parser.js:846`

The parser constructs a RegExp object from user-supplied pattern and flags (peg$c76). This is standard for CSS/selector parsers and is not inherently malicious, but if the parser output is consumed without validation, a crafted regex could cause ReDoS. No other risky patterns were found.

## Files reviewed

- `parser.js` (safe): This is a standard PEG.js-generated selector parser with no malicious patterns; only a benign dynamically constructed RegExp from parsed input was noted.
