spacecode@2.16.56
SpaceCode - launch cloud dev environments with AI coding agents
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe REPL accepts an unrestricted endpoint override while forwarding a resolved key, creating conditional credential exposure. Because the endpoint is explicitly operator-configured and defaults to SpaceCode’s host, this supports a warning rather than 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
Trigger
Run the REPL with API_PROXY_URL set and a key available through its environment or saved auth file.
Impact
The key may be disclosed to the configured endpoint; the inspected source does not establish that the override is malicious or that this is a fixed publisher-selected destination.
Mechanism
The REPL resolves a key, supplies it with the configured API URL to its model client, and sends it in an API request header.
AI rationale
The REPL accepts an unrestricted endpoint override while forwarding a resolved key, creating conditional credential exposure. Because the endpoint is explicitly operator-configured and defaults to SpaceCode’s host, this supports a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The REPL loads keys from SPACECODE_API_KEY, ANTHROPIC_API_KEY, or the saved SpaceCode auth file.
- The model endpoint can be overridden with API_PROXY_URL; otherwise it defaults to SpaceCode’s API host.
- The REPL combines the selected endpoint and resolved key, then sends requests to its messages API with the key in a request header.
- The CLI’s separate proxy path uses the literal value "proxy" by default and points to SpaceCode’s API host.
Evidence against
- The endpoint override is explicitly read from the operator’s environment; the default destination is SpaceCode’s API host.
- The manifest declares CLI entry points but 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.
