- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 0.2.6
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The user-invoked CLI and import entry point load heavily obfuscated code that includes file and process primitives. No install-time execution or confirmed hostile endpoint was found.

## Security analysis

### Published attack-surface review

- **Summary:** The user-invoked CLI and import entry point load heavily obfuscated code that includes file and process primitives. No install-time execution or confirmed hostile endpoint was found.

- **Trigger:** Importing dist/index.js or running the cxu command.

- **Impact:** The concealed implementation cannot be safely validated; its runtime capabilities could affect local files or processes.

- **Evidence paths:** dist/index.js, dist/cli.js, package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-09-13T05:22:31.828Z

### AI review details

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

- **Mechanism:** Obfuscated runtime with file and process capabilities.

- **Rationale:** The package deliberately obfuscates its published runtime but has no registry install lifecycle hook or self-dependency chain. Static inspection did not establish a concrete malicious action, so blocking is not justified.

- **Files touched:** dist/index.js, dist/cli.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 78.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The published main module is deliberately obfuscated, preventing reliable static validation of its file, process, and network behavior., The manifest intentionally runs an obfuscation step before packing the release.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., No runtime dependency on this package name was found., No concrete credential theft, destructive action, or unconsented install-time mutation was established by source inspection.

## Affected versions and remediation
