## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 17 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 5.5.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Installation retrieves and loads a native module from a proxy-mediated remote source without an integrity check. This creates an automatic remote native-code execution path if that delivery path is compromised.

## Security analysis

### Published attack-surface review

- **Summary:** Installation retrieves and loads a native module from a proxy-mediated remote source without an integrity check. This creates an automatic remote native-code execution path if that delivery path is compromised.

- **Trigger:** npm installation invokes the postinstall lifecycle hook.

- **Impact:** A compromised proxy, redirect target, or release asset could execute code with the installing user's privileges.

- **Evidence paths:** package.json, postinstall.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-29T15:32:02.481Z

### AI review details

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

- **Mechanism:** The hook downloads native/jsql-neo-native.node, follows redirects, and loads it using Node's native-module loader.

- **Rationale:** The automatic, unverified download and loading of native code is a critical remote-code-execution risk. The source does not provide sufficient evidence of malicious author intent, so warning is appropriate.

- **Files touched:** native/jsql-neo-native.node

- **Network endpoints:** https://gh-proxy.com/

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 93.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Low

- **Evidence for warning:** The package automatically runs postinstall.js during installation., The installer downloads a native module through an external proxy into the package and then loads it with require., The download routine accepts redirects and has no visible integrity or signature verification before native-code loading.

- **Evidence against:** The download URL is constructed for a versioned release asset from the package repository., The installer falls back to building the bundled native source when download fails.

## Affected versions and remediation

This report applies to jsql-neo@5.5.0.

- Review the evidence and your use of jsql-neo@5.5.0 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
