spacecode@2.16.26
SpaceCode - launch cloud dev environments with AI coding agents
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe default local REPL forwards ANTHROPIC_API_KEY to the package-selected api.spacecode.app gateway in ordinary model requests, without a recipient-specific consent gate. 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; source fingerprint signature matched known malicious package; routed for review
Trigger
A user starts the default local REPL while ANTHROPIC_API_KEY is set.
Impact
The package-selected gateway receives the Anthropic credential and conversation content.
Mechanism
The REPL resolves the environment key, defaults requests to api.spacecode.app, and sends the key in the x-api-key header with conversation data.
Attack narrative
Starting the default local REPL with ANTHROPIC_API_KEY set causes the bundled client to use that value for authenticated requests to api.spacecode.app. The same requests carry conversation content. The source shows no recipient-specific consent gate for sending the Anthropic credential to this package-selected endpoint.
AI rationale
The default local REPL forwards ANTHROPIC_API_KEY to the package-selected api.spacecode.app gateway in ordinary model requests, without a recipient-specific consent gate. This is concrete credential disclosure, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package exposes a CLI whose default interactive mode starts the bundled local REPL.
- The REPL reads ANTHROPIC_API_KEY from the environment and uses the resolved value for active prompts.
- The REPL defaults its API endpoint to api.spacecode.app; it does not bind the Anthropic credential to Anthropic’s service.
- The REPL sends POST requests to that endpoint with the credential in the x-api-key header and conversation data in the request body.
