Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 17 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.25 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The inspected lifecycle script does not run its nested installation logic for normal npm dependency installs, and the active launcher and client behavior are package-aligned local-server functions. No concrete malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-27T04:13:14.260Z - **Finished:** 2026-09-27T04:15:40.162Z - **Download time:** 1014 ms - **Static scan time:** 2949 ms - **AI review time:** 141938 ms - **Total time:** 145902 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 surface was identified from the inspected package entrypoints. The package provides a local notebook server and browser client. - **Trigger:** A user installs the package or explicitly runs its command-line launcher. - **Impact:** No confirmed credential exfiltration, remote payload execution, persistence, destructive action, or foreign agent-control mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-27T04:15:40.162Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook exits for node\_modules installations; the launcher starts the packaged server, which exposes local application functionality. - **Rationale:** The inspected lifecycle script does not run its nested installation logic for normal npm dependency installs, and the active launcher and client behavior are package-aligned local-server functions. No concrete malicious behavior was identified. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package defines a postinstall hook that invokes its included script., The command-line launcher starts the included server entry with caller-provided arguments., The resource service queries local GPU status with nvidia-smi., The postinstall script exits when installed under node\_modules, avoiding subpackage installation for registry consumers., The browser client sends its authentication status request to the relative /api endpoint., The server starts a Fastify listener using its configured local bind host and port. ## Affected versions and remediation This report applies to nebula-notebook@0.2.25. - Review the evidence and your use of nebula-notebook@0.2.25 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.
