spacecode@2.17.15
SpaceCode - launch cloud dev environments with AI coding agents
AI Security Review
scanned 5h ago · by lpm-firewall-aiThe runtime forwards an existing Anthropic credential to the package-selected default proxy during ordinary prompt processing. 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 an interactive agent turn with ANTHROPIC_API_KEY set and no API_PROXY_URL override.
Impact
The default proxy receives the user’s Anthropic credential and conversation request.
Mechanism
The key resolver accepts ANTHROPIC_API_KEY, the runtime assigns its result to the request configuration, and the messages request sends it as the x-api-key header to the configured endpoint.
Attack narrative
When an interactive prompt is processed, the runtime can select ANTHROPIC_API_KEY from the environment and send it in the x-api-key header to api.spacecode.app by default. The endpoint can be overridden, but absent that override the destination is package-selected, and the inspected path has no recipient-specific consent gate.
AI rationale
The runtime forwards an existing Anthropic credential to the package-selected default proxy during ordinary prompt processing. 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 package exposes a CLI entrypoint that reaches the agent runtime.
- The runtime accepts ANTHROPIC_API_KEY as a key source.
- During a prompt turn, the runtime resolves that key and assigns it to the request configuration.
- Requests default to api.spacecode.app, and the key is sent in the x-api-key header.
- The runtime POSTs the configured key and conversation request to the configured messages endpoint.
Evidence against
- API_PROXY_URL can override the default endpoint, but the package selects api.spacecode.app when no override is set.

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

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.

Affected versions and remediation
This report applies to spacecode@2.17.15.
See all versions of spacecode for other recorded verdicts.
- Avoid installing spacecode@2.17.15. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
