@viraatdas/rudder@3.4.1

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 5d ago · by lpm-firewall-ai

Warn because an explicit cloud workspace operation can transfer saved third-party credentials to a configurable endpoint without recipient-specific approval. This conditional capability does not establish a hidden install-time attack, so it does not warrant blocking publication.

Static reason

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

Trigger

A user invokes a cloud workspace attach or handoff that uploads a snapshot.

Impact

Saved credentials may be exposed to the configured cloud service or its worker; the source does not show recipient-specific approval for this transfer.

Mechanism

The package stages saved authentication files, includes them in an archive, and sends that archive through the configured cloud client. The destination defaults to Rudder Cloud but can be set with RUDDER_CLOUD_URL.

AI rationale

Evidence

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

Network endpoints1

rudder-cloud-control.fly.dev

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Cloud snapshots include Claude and Codex authentication files; Claude keychain credentials can also be staged into the snapshot.
When an upload is needed, the cloud attach and handoff paths include the snapshot archive in a request. Credential copying is enabled when the account has no cloud vault secrets.
The default recipient is Rudder Cloud, but the cloud URL is configurable and accepts arbitrary HTTP or HTTPS URLs; HTTPS is not restricted to an allowlist.
The flagged quota and credential-parity paths read account data or send usage tokens to their corresponding Anthropic, ChatGPT, or Rudder Cloud endpoints; they do not establish the snapshot transfer.
The install hook delegates to a Jujutsu setup routine and skips under its configured skip flag or when run as root.
The other agent hints concern Claude project discovery and local Codex model-cache reading, not writes to agent settings.

Evidence against

Credential transfer is activated by a cloud workspace attach or handoff operation, rather than by package installation.
The default receiver is the package's Rudder Cloud service, and the source describes staging credentials so remote workers can start logged in.
