## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 28 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 3.5.6
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Cloud snapshots can include local credentials and are sent to RUDDER\_CLOUD\_URL, which accepts custom HTTPS hosts without a host allowlist. The package-aligned default and user-invoked cloud commands limit this to conditional credential exposure, so a warning is appropriate.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 84.0%
- **Started:** 2026-10-20T04:30:15.602Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** A cloud snapshot can contain local credentials and be sent to a custom control-plane host. This creates conditional credential exposure when that host is configured outside Rudder Cloud.

- **Trigger:** A user invokes a cloud launch, workspace attach, or handoff while RUDDER\_CLOUD\_URL points to a custom host.

- **Impact:** The configured recipient may receive saved provider credentials and other included local files without a separate confirmation for that recipient.

- **Evidence paths:** dist/cloud.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-20T04:35:53.962Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Snapshot creation includes credentials by default on some paths and stages credentials when enabled on others. The CLI accepts HTTPS control-plane URLs without restricting their host and posts the snapshot archive there.

- **Rationale:** Cloud snapshots can include local credentials and are sent to RUDDER\_CLOUD\_URL, which accepts custom HTTPS hosts without a host allowlist. The package-aligned default and user-invoked cloud commands limit this to conditional credential exposure, so a warning is appropriate.

- **Files touched:** dist/cloud.js

- **Network endpoints:** https://rudder-cloud-control.fly.dev

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 84.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json runs scripts/postinstall.mjs. That hook calls the workspace-engine setup helper; the helper uses an existing jj binary or installs Rudder's managed version., Cloud snapshots include local credentials by default and can stage a Claude Keychain credential. The archive is sent to the configured control plane; RUDDER\_CLOUD\_URL accepts HTTPS URLs without a host allowlist. The default is Rudder Cloud, and a saved Rudder login token is reused only when its saved URL matches., The inspected agent and usage paths read local conversation or model data, compare local and cloud credential status, or send a Codex usage token to ChatGPT's usage endpoint. The board serves quota results locally and restricts requests to loopback., The flagged runtime operations perform text formatting and secret redaction, run a supplied command with supplied arguments, rebroadcast board updates, or upload clipboard files during an interactive cloud workspace session., The improvement scheduler is installed through an explicit command, and its default autonomy is propose rather than unattended release. Other reviewed runtime paths include local session collection, backend selection, user-started runs, update checks, feedback submission, and checksum-pinned workspace-engine setup.

- **Evidence against:** The cloud feature's default destination is Rudder Cloud, and saved Rudder authentication is not reused when the configured URL differs from the saved URL., The inspected source does not show recipient-specific confirmation before snapshot credentials are sent to a custom control-plane URL.

## Affected versions and remediation

This report applies to @exla/rudder@3.5.6.

- Review the evidence and your use of @exla/rudder@3.5.6 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
