## Verdict summary
**Blocked & quarantined** — The gateway receives the Anthropic credential, allowing exposure beyond its intended service.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 2.16.65
- **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The REPL forwards an existing Anthropic credential to a package-selected gateway without recipient-specific consent. The gateway’s product alignment does not establish that the user authorized exporting credentials intended for Anthropic.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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:** The REPL can send an existing Anthropic API key to the SpaceCode gateway during a model request.

- **Trigger:** A user submits a prompt in the bundled local REPL while an Anthropic API key is available in the environment.

- **Impact:** The gateway receives the Anthropic credential, allowing exposure beyond its intended service.

- **Evidence paths:** package.json, dist/repl.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T19:37:24.438Z

### AI review details

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

- **Mechanism:** The REPL resolves that key and includes it in the request to its default gateway, without a recipient-specific confirmation.

- **Attack narrative:** When a user submits a prompt, the REPL can resolve ANTHROPIC\_API\_KEY and send it as the authentication key for a request to the default SpaceCode gateway. The source shows no recipient-specific confirmation for forwarding that existing Anthropic credential.

- **Rationale:** The REPL forwards an existing Anthropic credential to a package-selected gateway without recipient-specific consent. The gateway’s product alignment does not establish that the user authorized exporting credentials intended for Anthropic.

- **Files touched:** dist/repl.mjs

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 88.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The shipped REPL accepts an existing Anthropic API key or saved authentication token as its API key., After a prompt, the REPL uses the package’s default SpaceCode gateway and sends the key in an authenticated model request., The package manifest includes the REPL bundle in its distributed files.

- **Evidence against:** The gateway belongs to the SpaceCode service, and the source presents it as the REPL’s model gateway.

## Affected versions and remediation

This report applies to spacecode@2.16.65.

- Avoid installing spacecode@2.16.65. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
