## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The install hook enforces the declared Node.js engine requirement, and the inspected media helper streams a URL supplied to it.

- **Trigger:** Package installation triggers the preinstall engine check; callers invoke the media helper with a URL to stream.

- **Impact:** No malicious install-time mutation or credential exfiltration was established from the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T22:03:12.702Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The engine check exits for Node versions below 20. The media helper uses axios to GET the supplied URL and returns the response stream.

- **Rationale:** The manifest’s preinstall script runs a straightforward Node version check, while the flagged network code is a caller-supplied media fetch. The inspected required source files contain no evidence of malicious behavior.

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The preinstall hook only invokes an engine check that exits on Node versions below 20., The required version data file contains only a WhatsApp protocol version tuple., The flagged media code performs an HTTP GET for a supplied URL to stream media; no credential forwarding or unrelated destination is shown.

## Affected versions and remediation
