## Summary

Togoder Security scanned the npm package form-data@4.0.6 on Oct 4, 2026. An AI review of 3 source files produced 2 low severity findings. No malicious behavior, install-time payloads, credential theft or exfiltration were identified.

## Findings

### [low] Dynamic Header Injection Protected

Finding ID: `NPS-913EAB86A820`

File: `lib/form_data.js:22`

The code includes escapeHeaderParam() to sanitize CR/LF/quote characters in field names and filenames, mitigating header injection / multipart part smuggling. Custom options.header values are used as-is, which is expected library behavior and caller-controlled.

### [low] HTTP Request Capability

Finding ID: `NPS-8EA44EF661AA`

File: `lib/form_data.js:327`

The module includes a submit() method that can send the form data to an HTTP/HTTPS endpoint via http.request/https.request. However, this is a documented, intentional feature for submitting forms and not hidden exfiltration; it is invoked only by the caller.

## Files reviewed

- `lib/browser.js` (safe): Cleared by Jev triage; no further analysis needed
- `lib/form_data.js` (safe): This is the legitimate form-data library; no malicious patterns such as exfiltration, credential harvesting, obfuscation, backdoors, child_process execution, or install-time hooks were detected.
- `lib/populate.js` (safe): Cleared by Jev triage; no further analysis needed
