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 makes a bundled, source-unaccounted native server executable runnable. Runtime client and CLI paths can launch it locally; no confirmed outbound endpoint is present in reviewed JS. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-08-09T11:57:20.671Z - **Finished:** 2026-08-09T11:58:48.197Z - **Download time:** 501 ms - **Static scan time:** 1567 ms - **AI review time:** 85456 ms - **Total time:** 87526 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation makes a bundled, source-unaccounted native server executable runnable. Runtime client and CLI paths can launch it locally; no confirmed outbound endpoint is present in reviewed JS. - **Trigger:** npm install chmods it; HttpJSQL.start() or explicit CLI server use launches it - **Impact:** Unverifiable native code can run in the consumer environment when the server feature is used. - **Evidence paths:** package.json, postinstall.js, lib/client.js, bin/jsql-neo-server, nativesrc/jsql-neo-native/Cargo.toml - **Review source:** ai\_review - **Reviewed:** 2026-08-09T11:58:48.197Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** opaque bundled native-server execution - **Rationale:** No concrete malicious chain is established, but an install-enabled opaque executable lacks corresponding source and is a meaningful staged-payload risk. Warn pending reproducible source coverage for the server binary. - **Files touched:** package.json, postinstall.js, lib/client.js, bin/jsql-neo-server, bin/jsql, bin/jsql-server-control.js, nativesrc/jsql-neo-native/src/lib.rs ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** postinstall.js chmods bundled executable, bin/jsql-neo-server is an opaque 8.1 MB ELF, No source or Cargo manifest for that server executable is shipped, The executable is launched by lib/client.js on API use - **Evidence against:** postinstall.js does not launch the executable when present, No JS credential harvesting or external exfiltration found, JS HTTP requests target the configured local server, Dynamic plugin loading requires explicit user CLI registration ## Affected versions and remediation This report applies to jsql-neo@5.1.1. - Review the evidence and your use of jsql-neo@5.1.1 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. ## Public findings ### 1.
