spacecode@2.17.5
SpaceCode - launch cloud dev environments with AI coding agents
AI Security Review
scanned 11h ago · by lpm-firewall-aiThe source confirms that an ambient Anthropic key can be sent to the SpaceCode API during user-invoked REPL features, and that environment settings can redirect the recipient. This supports a warning for conditional credential exposure, but does not establish malicious intent or a covert default transfer.
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
The user invokes a REPL feature that uses the profile or memory API.
Impact
The key may be disclosed to the configured service, including a recipient selected through environment settings.
Mechanism
The REPL resolves a key from environment variables or saved authentication, then includes it in authenticated requests to the configured backend.
AI rationale
The source confirms that an ambient Anthropic key can be sent to the SpaceCode API during user-invoked REPL features, and that environment settings can redirect the recipient. This supports a warning for conditional credential exposure, but does not establish malicious intent or a covert default transfer.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The REPL accepts ANTHROPIC_API_KEY as an API key and can also read a saved key from auth.json.
- When the user invokes the skills feature, the REPL passes the resolved key to a client using the configured backend URL.
- That client sends the key as a bearer credential to the backend; memory requests also send the key to their configured base URL.
- The default backend is backend.spacecode.app, while environment variables can change the recipient.

•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:

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");

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