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 automatically retrieves and loads a native module from a remote release path. Redirect targets are not host-restricted and the artifact is not integrity-verified before loading. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-29T15:30:52.978Z - **Finished:** 2026-09-29T15:31:58.757Z - **Download time:** 758 ms - **Static scan time:** 2049 ms - **AI review time:** 62958 ms - **Total time:** 65779 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 automatically retrieves and loads a native module from a remote release path. Redirect targets are not host-restricted and the artifact is not integrity-verified before loading. - **Trigger:** npm installation invokes the postinstall lifecycle hook. - **Impact:** A compromised proxy, release asset, or redirect target could execute native code with the installing user's privileges. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T15:31:58.757Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook downloads a native binary, follows redirect locations, writes it to the native module path, and requires it. - **Rationale:** The automatic, unverified remote native-binary load is a concrete install-time remote-code-execution risk. The inspected code does not establish a separate malicious objective such as credential theft or persistence. - **Files touched:** postinstall.js, native/jsql-neo-native.node - **Network endpoints:** https://gh-proxy.com/, https://github.com/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest automatically runs postinstall.js during installation., The install handler downloads a platform-native module through a proxy URL into the package native path., The downloader follows redirect destinations without restricting their host, and the handler loads the resulting native module., Database persistence is scoped to the caller-provided database directory. - **Evidence against:** No self-dependency is declared., No credential collection or outbound credential transmission was identified in the inspected paths. ## Affected versions and remediation This report applies to jsql-neo@5.4.1. - Review the evidence and your use of jsql-neo@5.4.1 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.
