spacecode@2.17.17

SpaceCode - launch cloud dev environments with AI coding agents

AI Security Review

scanned 4h ago · by lpm-firewall-ai

The source does not substantiate the scanner's credential-redirection finding: login targets the SpaceCode auth service, and the API URL override is an explicit configuration action. The inspected dependencies and executable entry points revealed no separate attack behavior.

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 invokes login, configures an API URL, or uses the REPL service.

Impact

No credential theft or unrelated recipient was established from the inspected source.

Mechanism

Login obtains a key from the SpaceCode auth service and stores it locally; service requests send credentials to the configured API endpoint.

Decision evidence

public snapshot

AI called this Clean at 93.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest exposes CLI entry points and declares dependencies without lifecycle scripts.
Login sends device-token requests to the SpaceCode auth service and saves the returned key locally.
Credentialed service requests use SpaceCode API defaults; a custom API URL is set explicitly through configuration.
The REPL sends its API key to its configured gateway for service requests, whose default is the SpaceCode API host.
The inspected dependency snapshots show standard Chalk imports and Commander CLI exports; no dependency attack behavior was identified.
