## Verdict summary
**Blocked & quarantined** — A third party can receive and potentially use the active API credential, plus spoken response text.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 0.17.7
- **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

Speak mode sends the active model-provider API key and response text to a fixed xAI TTS endpoint. The active key can belong to OpenAI or Anthropic rather than xAI.

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:** Speak mode sends the active model-provider API key and response text to a fixed xAI TTS endpoint. The active key can belong to OpenAI or Anthropic rather than xAI.

- **Trigger:** A user enables /speak in an interactive session and the assistant produces a response.

- **Impact:** A third party can receive and potentially use the active API credential, plus spoken response text.

- **Evidence paths:** src/cli.js, src/voice.js, src/model-catalog.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-13T15:05:54.606Z

### AI review details

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

- **Mechanism:** Cross-provider API credential disclosure through fixed TTS authorization.

- **Attack narrative:** The CLI exposes an interactive speak mode. When enabled, each assistant response calls speakFull with context.runtime.apiKey. That function ignores the selected provider URL and posts the response text to api.x.ai using that key as a Bearer token. The provider catalog shows that the same runtime key may instead be an OpenAI or Anthropic key. Thus enabling TTS can disclose a credential to an unrelated fixed service.

- **Rationale:** The fixed xAI TTS request forwards the active runtime credential without ensuring it is an xAI credential. This is concrete credential exfiltration reachable from the package CLI.

- **Network endpoints:** api.x.ai

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The /speak feature passes the active runtime API key into the TTS call., The TTS call always posts that key as Bearer authorization to api.x.ai., The runtime supports separate OpenAI and Anthropic credentials, so this can disclose a non-xAI key., The key transfer occurs after a user enables speak mode and receives a response.

- **Evidence against:** package.json has no npm install lifecycle hook., The listen-agent persistence path is only reached by an explicit listen install command.

## Affected versions and remediation

This report applies to @tritard/waterbrother@0.17.7.

- Avoid installing @tritard/waterbrother@0.17.7. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
