## 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:** 0.2.30
- **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 install hook is explicitly disabled for npm dependency installs, while the flagged process and file operations are runtime features of the notebook application. Source inspection found no concrete malicious chain.

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 confirmed malicious attack surface was established. The package is a notebook server with deliberate, user-invoked terminal and file-management features.

- **Trigger:** A user runs the nebula-notebook command and interacts with its local server.

- **Impact:** It can operate on files and shells selected through the running notebook service; no unconsented install-time or covert exfiltration behavior was found.

- **Evidence paths:** package.json, scripts/postinstall.cjs, bin/nebula-notebook.js, node-server/dist/update-check.js, node-server/dist/terminal/pty-manager.js, node-server/dist/fs/fs-service.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-27T19:18:38.195Z

### AI review details

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

- **Mechanism:** User-invoked notebook, filesystem, and terminal service.

- **Rationale:** The install hook is explicitly disabled for npm dependency installs, while the flagged process and file operations are runtime features of the notebook application. Source inspection found no concrete malicious chain.

- **Files touched:** scripts/postinstall.cjs, bin/nebula-notebook.js, node-server/dist/update-check.js, node-server/dist/terminal/pty-manager.js, node-server/dist/fs/fs-service.js

- **Network endpoints:** https://registry.npmjs.org/nebula-notebook/latest

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest defines a postinstall hook., The runtime server can create user-facing terminal sessions and manage notebook files.

- **Evidence against:** The postinstall script exits when installed under node\_modules, so published dependency installation does not run its nested npm installs., The command-line launcher only starts the bundled local server and forwards user-supplied arguments., The only fixed outbound endpoint found is the npm registry version check; it reads a version and logs an update notice., No credential harvesting, external payload download, obfuscated loader, or foreign AI-agent configuration mutation was found.

## Affected versions and remediation
