spacecode@2.16.68
SpaceCode - launch cloud dev environments with AI coding agents
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe active REPL path forwards an Anthropic API credential to the package's default gateway. This is a concrete credential disclosure supporting a block.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
A user submits a prompt in the SpaceCode REPL with ANTHROPIC_API_KEY set and no API_PROXY_URL override.
Impact
The SpaceCode gateway receives the caller's Anthropic API credential and prompt data.
Mechanism
The REPL resolves ANTHROPIC_API_KEY, uses the package default gateway URL, and places the key in the model request headers.
Attack narrative
On a submitted REPL prompt, the package accepts ANTHROPIC_API_KEY as the active API key and sends it in an authenticated model request. When the caller has not overridden API_PROXY_URL, that request goes to the package-selected SpaceCode gateway, exposing an Anthropic credential to a different recipient without recipient-specific consent shown in the inspected source.
AI rationale
The active REPL path forwards an Anthropic API credential to the package's default gateway. This is a concrete credential disclosure supporting a block.
Evidence
dist/repl.mjs

api.spacecode.app
Decision evidence
public snapshotAI called this Malicious at 88.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package exposes a CLI whose REPL is bundled in dist/repl.mjs.
- The REPL automatically reads ANTHROPIC_API_KEY as an API credential, alongside SpaceCode-specific credentials.
- Without an API_PROXY_URL override, the REPL targets https://api.spacecode.app.
- When a user submits a prompt, the REPL uses the resolved key in its model request headers and sends the request to the configured gateway.
Evidence against
- The gateway URL can be overridden through API_PROXY_URL, but the package-provided default remains in effect when no override is set.

•Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration.
dist/index.js:
baseUrl;
constructor(baseUrl, token) {
this.baseUrl = baseUrl ?? process.env.SPACECODE_API_URL ?? DEFAULT_API_URL;
const url = `${this.baseUrl}${path6}`;
headers["Authorization"] = `Bearer ${this.token}`;
throw new AuthError("Authentication failed. Please check your API key or run a command to re-authenticate");
const response = await fetch(`${this.baseUrl}/health`, {
const url = `${this.baseUrl}/api/auth/exchange`;

Credential Redirect Persistence
Manifest-reachable source sends a prompted API credential to a fixed unofficial gateway and persists the redirection.
