@viraatdas/rudder@3.1.12

A TUI for managing coding agents: run Claude Code, Codex and opencode side by side, each in its own isolated jj workspace.

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The source shows a reachable snapshot upload path that includes saved third-party credentials by default and sends the archive to a package-selected cloud recipient. That transfer supports blocking publication as credential exfiltration.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A user runs the cloud workspace flow for a repository without a GitHub origin, or requests a snapshot upload.

Impact

Saved credentials may be disclosed to the cloud service and used from the cloud workspace.

Mechanism

The snapshot collector copies local authentication files and stages Claude credentials; credential inclusion defaults on unless a cloud vault is active. The resulting archive is sent in a request to the Rudder cloud service.

Attack narrative

When the cloud snapshot path is used, the package gathers saved authentication files, including Claude credentials, unless the cloud vault is active. It places the snapshot archive in a request to the default Rudder cloud service. The inspected path does not establish recipient-specific consent for exporting those third-party credentials.

rudder-cloud-control.fly.dev

Decision evidence

public snapshot

AI called this Malicious at 92.0% confidence as Malware with low false-positive risk.

Evidence for block

The `rudder cloud` command can upload a local workspace snapshot when the repository lacks a GitHub origin.
Snapshot creation includes credentials unless the cloud vault is active, and the credentials flag is not a recipient-specific consent check.
Snapshot collection copies saved Claude credentials and Codex authentication files into the upload staging area.
The snapshot archive is sent to the configured Rudder cloud service, whose default host is rudder-cloud-control.fly.dev.

Evidence against

The package also has a postinstall hook that installs the ordinary `jj` version-control tool when missing; that hook does not establish the credential transfer.
