## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 4.5.2
- **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.

npm installation can invoke Cargo in an adjacent, foreign project when the package server binary is absent. This creates install-time code-execution exposure from a sibling directory, not a confirmed payload in this package.

## Security analysis

### Published attack-surface review

- **Summary:** npm installation can invoke Cargo in an adjacent, foreign project when the package server binary is absent. This creates install-time code-execution exposure from a sibling directory, not a confirmed payload in this package.

- **Trigger:** npm install with no bin/jsql-neo-server and a sibling ../jsql-neo-server/Cargo.toml

- **Impact:** A controllable sibling Cargo project could run with installer privileges.

- **Evidence paths:** package.json, postinstall.js, bin/jsql, bin/jsql-server-control.js, lib/mod.js, lib/client.js, nativesrc/jsql-neo-native/src/lib.rs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T11:54:19.279Z

### AI review details

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

- **Mechanism:** postinstall executes cargo build in a foreign sibling directory

- **Rationale:** This is not proven package malware, but its install hook executes an unrelated adjacent project under a condition common enough to create a real supply-chain code-execution risk.

- **Files touched:** postinstall.js, bin/jsql-neo-server, ../jsql-neo-server/Cargo.toml

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Low

- **Evidence for warning:** package.json runs postinstall.js on install., postinstall.js conditionally runs cargo build in ../jsql-neo-server., That adjacent project is outside this package and its Cargo build scripts can execute during install.

- **Evidence against:** No credential harvesting or outbound exfiltration found in inspected JS/Rust source., Runtime HTTP and socket use is for user-configured local database servers., Dynamic module loading requires an explicit jsql mod add path., Native and WASM sources implement local database storage.

## Affected versions and remediation

- Review the evidence and your use of jsql-neo@4.5.2 before allowing it. Restrict the permissions described in this report.
