spacecode@2.16.75
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 key to the package-selected SpaceCode gateway by default. This is concrete credential disclosure, so the package should be blocked.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
A user runs the local REPL with ANTHROPIC_API_KEY set and sends a prompt.
Impact
The SpaceCode gateway operator receives the user's Anthropic API key.
Mechanism
The key is used as the request API key and placed in the x-api-key header for a POST to the configured messages endpoint, which defaults to the SpaceCode gateway.
Attack narrative
A prompted REPL turn resolves ANTHROPIC_API_KEY as its API key, selects the package's default SpaceCode gateway, and sends the key in the x-api-key header. The endpoint override does not make the package-selected default a user-selected recipient. This exposes an Anthropic credential to a different service without recipient-specific consent.
AI rationale
The active REPL path forwards an Anthropic API key to the package-selected SpaceCode gateway by default. This is concrete credential disclosure, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
Evidence for block
- The CLI starts the bundled REPL, where ordinary prompted turns use the resolved API key.
- The key resolver accepts ANTHROPIC_API_KEY as an API key.
- The REPL defaults its model endpoint to https://api.spacecode.app; API_PROXY_URL can override that destination.
- The active request uses the configured endpoint and resolved key for a POST to its messages route.
- The POST sends the key in the x-api-key header.
Evidence against
- The endpoint can be changed through API_PROXY_URL, but the default destination is selected by the package.

•Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration.
