spacecode@2.16.55
SpaceCode - launch cloud dev environments with AI coding agents
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe source supports a warning because an unrestricted API URL override can receive the saved service token through ordinary authenticated requests. The default endpoint is package-aligned and no fixed unofficial recipient or other concrete attack behavior was established.
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
Trigger
A command that authenticates with a saved token while SPACECODE_API_URL or the saved API URL override is set.
Impact
A token may be exposed to an unintended configured endpoint.
Mechanism
The CLI uses the override as its backend base URL and adds the saved token to the Authorization header without restricting the destination to a SpaceCode host.
AI rationale
The source supports a warning because an unrestricted API URL override can receive the saved service token through ordinary authenticated requests. The default endpoint is package-aligned and no fixed unofficial recipient or other concrete attack behavior was established.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The normal backend defaults to SpaceCode, but the API URL can be overridden through environment or saved configuration.
- The CLI sends a saved authentication token to the configured API URL when checking the current user.
- The API client places its token in an Authorization header on requests to its base URL.
- A CLI configuration command saves a supplied API URL for later use.
Evidence against
- The inspected default backend is SpaceCode’s service; no fixed unofficial credential gateway was found.
- The API URL override is configurable by the operator, and the package manifest has no lifecycle scripts.

•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.
