Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection resolved the lifecycle, child-process, shell, and network hints as package setup or ordinary application behavior. No concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-18T12:46:47.318Z - **Finished:** 2026-10-18T12:47:51.666Z - **Download time:** 2045 ms - **Static scan time:** 3121 ms - **AI review time:** 59181 ms - **Total time:** 64348 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:** No attack was identified in the inspected source. The flagged process execution and network activity support package setup, resource reporting, and update notification. - **Trigger:** Package installation, launching the server, or server startup for the update check. - **Impact:** No confirmed harmful effect; the inspected behavior supports repository setup and normal application functions. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T12:47:51.666Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script exits under node\_modules; the launcher starts the packaged server, GPU collection uses fixed diagnostic commands, and the update checker requests the package version from the npm registry. - **Rationale:** Source inspection resolved the lifecycle, child-process, shell, and network hints as package setup or ordinary application behavior. No concrete attack behavior was established. - **Network endpoints:** https://registry.npmjs.org/nebula-notebook/latest ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines postinstall, but the script exits when run from node\_modules; its nested installs support repository checkout setup., The launcher starts the packaged server and forwards the caller’s arguments and environment., GPU resource collection runs fixed nvidia-smi and rocm-smi probes with timeouts; the source describes collection as optional., The update checker makes a bounded request to the npm registry to compare package versions., The inspected UI bundle contains notebook setup behavior, and the server bundle reads Jupyter configuration from a supplied config path; these excerpts do not establish an attack. - **Evidence against:** The inspected lifecycle hook does not run its nested installs for the normal node\_modules package installation path., The shell execution finding is explained by fixed GPU information probes; the inspected launcher starts the package’s server entrypoint. No concrete malicious behavior was identified. ## Affected versions and remediation This report applies to nebula-notebook@0.2.81. - Review the evidence and your use of nebula-notebook@0.2.81 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.
