# @tangle-network/sandbox-cli@0.21.50 npm security report

## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 16 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 0.21.50
- **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 hardcoded Tailscale-hosted relay is an unusual and unexplained trust dependency for signed Solve transactions, so users should be warned. The source does not show automatic activation, credential exfiltration, or another concrete attack, so the evidence does not support blocking the package as malicious.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious

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:** Solve transaction submission trusts a hardcoded Tailscale-hosted sponsor relay; no confirmed malicious behavior was identified.

- **Trigger:** Explicit use of \`tangle solve submit\`.

- **Impact:** The relay operator can observe and control delivery of signed competition transactions, creating a trust and availability risk. The inspected source does not show credential theft or unauthorized actions.

- **Evidence paths:** dist/index.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T10:40:47.077Z

### AI review details

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

- **Mechanism:** The CLI configures the wallet transaction transport with the hardcoded sponsor URL, so that relay receives transaction traffic and participates in its delivery.

- **Rationale:** The hardcoded Tailscale-hosted relay is an unusual and unexplained trust dependency for signed Solve transactions, so users should be warned. The source does not show automatic activation, credential exfiltration, or another concrete attack, so the evidence does not support blocking the package as malicious.

- **Files touched:** .tangle-solve-run.json

- **Network endpoints:** drew-gtr-pro.taild10bfc.ts.net, rpc.moderato.tempo.xyz

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 82.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The Solve configuration hardcodes https://drew-gtr-pro.taild10bfc.ts.net/solve-sponsor as its sponsor URL., Solve transactions use a wallet transport wrapped with withRelay and directed to the configured sponsor URL., The CLI exposes Solve submission as an explicit \`tangle solve submit\` command.

- **Evidence against:** The manifest exposes a CLI entry point and contains no preinstall, install, or postinstall script., Solve checkers run in a bubblewrap environment with network isolation., The source shows submission of checker evidence to the Solve API as part of the explicit submit flow; it does not establish credential exfiltration to the sponsor host.

## Affected versions and remediation
