## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 18 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 2.16.62
- **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 source supports a conditional credential-exposure warning: API requests forward the saved token to a configurable destination without an allowlist. The inspected default is SpaceCode’s backend, so this does not establish a fixed-recipient credential theft attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 84.0%
- **Started:** 2026-10-21T18:43:11.717Z
- **Finished:** 2026-10-21T18:44:15.720Z
- **Download time:** 1292 ms
- **Static scan time:** 4351 ms
- **AI review time:** 58359 ms
- **Total time:** 64003 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:** A saved SpaceCode API credential is sent with authenticated requests to the configured API URL. If that URL is set to an unrelated service, the credential is exposed to that recipient.

- **Trigger:** A user configures a custom API URL and runs a command that makes an authenticated API request.

- **Impact:** A configured recipient could receive the saved API credential. The inspected defaults point to SpaceCode services, and no fixed unrelated recipient was found.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T18:44:15.720Z

### AI review details

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

- **Mechanism:** The client selects the URL from configuration or an environment variable and adds the saved token as a bearer credential, without a destination allowlist.

- **Rationale:** The source supports a conditional credential-exposure warning: API requests forward the saved token to a configurable destination without an allowlist. The inspected default is SpaceCode’s backend, so this does not establish a fixed-recipient credential theft attack.

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

- **Network endpoints:** https://backend.spacecode.app

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 84.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Saved API credentials are passed to a client whose destination can come from an environment variable or saved configuration., Authenticated API requests send the saved token as a bearer credential., The package provides a command that saves a caller-supplied API URL for later use.

- **Evidence against:** The default API and proxy hosts belong to SpaceCode., Device login presents a sign-in code for user approval; the inspected source does not show a fixed unrelated credential recipient.

## Affected versions and remediation
