@viraatdas/rudder@3.1.20

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 package has a concrete, conditionally activated path that copies saved third-party credentials into a snapshot sent to Rudder Cloud without recipient-specific consent. Because this occurs through an explicit cloud workspace feature rather than an ordinary login path, warn rather than block.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

A user runs the cloud workspace attach flow and it falls back to uploading a snapshot.

Impact

The cloud worker can receive credentials for signed-in third-party accounts. The source does not show recipient-specific consent for that transfer.

Mechanism

The snapshot copies credential files and stages Claude Keychain credentials; credentials are included unless the vault check succeeds, then the archive is posted to the configured Rudder Cloud control plane.

AI rationale

Evidence

dist/cloud.jspackage.json~/.claude/.credentials.json~/.codex/auth.json

Network endpoints1

rudder-cloud-control.fly.dev

Decision evidence

public snapshot

AI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

When a cloud workspace needs a snapshot, the default path includes saved Claude and Codex credentials; it stages those files unless the account already has vault secrets.
The snapshot is sent in a POST to the Rudder Cloud workspace endpoint, whose default host is rudder-cloud-control.fly.dev. The source shows no separate recipient-specific confirmation before including saved credentials.

Evidence against

The usage feature sends Claude and Codex bearer tokens to their respective service usage endpoints, which is ordinary authentication to those services.
Other flagged locations read local account identity, conversation, and model-cache data or serve quota data through a loopback board; those excerpts do not establish a separate credential attack.
