spacecode@2.16.20

SpaceCode - launch cloud dev environments with AI coding agents

AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection found no lifecycle hooks and did not substantiate the scanner’s credential-redirection claim. The flagged agent-related code reads or scans project files; no attack surface was established.

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

Running a package command or its MCP entrypoint.

Impact

No credential redirection or agent configuration mutation was established from the inspected source.

Mechanism

The inspected login code validates a SpaceCode API key and saves it locally; the flagged agent-related locations scan or read project files.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

The manifest defines CLI and MCP entrypoints and contains no lifecycle script.
The login command validates supplied SpaceCode API keys and saves them through the local auth-storage helper.
The configured API endpoints use SpaceCode domains.
The flagged CLI location scans files and skips the .claude directory; the flagged REPL location reads project-local Claude command files.
The MCP entrypoint is a command-line server, with no install-time behavior identified.

Evidence against

The scanner’s credential-redirect claim was not supported by the inspected login path: the supplied API key is saved locally, and the inspected default API endpoints are SpaceCode domains.
