voice

• Outcome: Review
• Latest audit: Sep 16, 2026 · 5:59 AM UTC
• Version: 1.0.0

Overview

This appears to be a real Discord voice assistant plugin, but it needs Review because voice access, provider credentials, and conversation data are broader and less clearly scoped than users are likely to expect.

Install only after deciding that Discord voice participants may send prompts to the main agent and after configuring allowedUsers or other channel controls. Use plugin-specific, revocable, capped credentials, verify whether SkillBoss/HeyBossAI processing is acceptable for your data, prefer local/offline providers for sensitive conversations, and update or review the dependency lockfile before production use.

{ // Convert raw PCM to WAV, then base64-encode for SkillBoss API Hub /v1/pilot const wavBuffer = this.pcmToWav(audioBuffer, sampleRate); const audiob64 = wavBuffer.toString("base64"); const response = await fetch("https://api.heybossai.com/v1/pilot", { method: "POST", headers: { Authorization: `Bearer ${this.apiKey}`, "Content-Type": "application/json", }, body: JSON.stringify({ type: "stt", inputs: { audio_data: audiob64, filename: "audio.wav" }, }), }); ``` Text-to-speech sends the agent's response text through the same intermediary: ```ts async synthesize(text: string): Promise { // TTS via SkillBoss API Hub /v1/pilot — auto-routes to best TTS model const response = await fetch("https://api.heybossai.com/v1/pilot", { method: "POST", headers: { Authorization: `Bearer ${this.apiKey}`, "Content-Type": "application/json", }, body: JSON.stringify({ type: "tts", inputs: { text, voice: this.voice }, prefer: "balanced", }), }); ``` ### Technical Analysis Remote transmission of audio and text is necessary when the user deliberately selects a cloud STT or TTS provider. However, the Skill describes provider choices such as OpenAI, ElevenLabs, and Deepgram while batch processing routes the actual content through `api.heybossai.com`. This creates an additional data-processing boundary that is not inherent to the declared provider functionality. Voice recordings may contain names, authentication information, private conversa ...[truncated 1534 chars]

Findings (85)

Known Vulnerable Dependency: protobufjs==7.5.4 — 12 advisory(ies): CVE-2026-44294 (protobuf.js: Denial of service from crafted field names in generated code); CVE-2026-44293 (protobuf.js: Code injection through bytes field defaults in generated toObject c); CVE-2026-44289 (protobuf.js: Denial of service through unbounded protobuf recursion) +9 more

Critical

• Category: Supply Chain
• Confidence: 95% confidence

Finding

The lockfile includes protobufjs 7.5.4, which the supplied advisory data marks as affected by multiple serious issues including denial of service, recursion abuse, and code-injection flaws in generated code paths. Even though a lockfile alone does not prove exploitability, this is a real supply-chain risk because the package is present multiple times transitively and could be invoked by tooling or runtime features that parse or generate protobuf content.

Content

Known Vulnerable Dependency: @hono/node-server==1.19.9 — 3 advisory(ies): CVE-2026-39406 (@hono/node-server: Middleware bypass via repeated slashes in serveStatic); GHSA-frvp-7c67-39w9 (Node.js Adapter for Hono: Path traversal in `serve-static` on Windows via encode); CVE-2026-29087 (@hono/node-server has authorization bypass for protected static paths via encode)

High

• Category: Supply Chain
• Confidence: 88% confidence

Finding

@hono/node-server 1.19.9 is listed with path traversal and middleware bypass issues in static-file handling. In this package context, Hono is a declared dependency and a voice bot may expose HTTP endpoints, so a vulnerable adapter could allow access-control bypass or unintended file exposure if static serving is used.

Known Vulnerable Dependency: sharp==0.34.5 — 2 advisory(ies): GHSA-f88m-g3jw-g9cj (sharp inherited vulnerabilities in libvips: CVE-2026-33327, CVE-2026-33328, CVE-); GHSA-rgj7-g3m4-5g8c (sharp: Vulnerabilities in libheif: GHSA-g89c-p67h-r497 and GHSA-2jg2-4ch7-h545)

High

• Category: Supply Chain
• Confidence: 83% confidence

Finding

sharp 0.34.5 is flagged due to inherited vulnerabilities in bundled/native image-processing libraries such as libvips/libheif. This is a real dependency risk because native parsers handling untrusted media can enable crashes, memory corruption, or malicious file-triggered denial of service when image features are reachable.

Known Vulnerable Dependency: @mariozechner/pi-coding-agent==0.52.12 — 3 advisory(ies): CVE-2026-54326 (Pi Agent: Potential XSS in HTML session exports via Markdown URL sanitization by); CVE-2026-54328 (Pi Agent: Predictable temporary extension install paths allow local privilege es); CVE-2026-54327 (Pi Agent: Race condition in Pi auth.json writes could expose stored credentials)

High

• Category: Supply Chain
• Confidence: 80% confidence

Finding

@mariozechner/pi-coding-agent 0.52.12 is marked with XSS, predictable temp path, and credential exposure issues. Although it appears as a transitive peer-related package from openclaw rather than a direct functional dependency of the voice skill, its presence still creates risk if bundled tooling, exports, auth storage, or extension-install flows are available in the execution environment.

Possible Typosquatting: 'oxlint' resembles popular package 'eslint'

High

• Category: Supply Chain
• Confidence: 70% confidence

Finding

Package name closely resembles a popular package, suggesting possible typosquatting. Attackers publish malicious packages with similar names to trick developers into installing them.

Intent-Code Divergence

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The class comment states that 'ElevenLabs supports streaming via their streaming endpoint' and that audio chunks are returned as generated, yet the implementation calls the SkillBoss /v1/pilot endpoint, fetches an audio_url afterward, and returns false from supportsStreaming(). This directly contradicts the documented intent of using ElevenLabs' streaming endpoint.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The skill explicitly supports multiple third-party STT/TTS providers and routes transcribed speech through external services, but the description does not clearly warn users that voice audio and transcript content may leave Discord and be sent to OpenAI, Deepgram, ElevenLabs, or related providers. This creates a meaningful privacy and consent risk because users in a voice channel may not realize their speech is being recorded, transcribed, and processed by external APIs.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The manifest explicitly advertises real-time voice conversations and configurable remote STT/TTS providers, yet it does not disclose that user audio and transcribed content may be sent to third-party services such as OpenAI, Deepgram, ElevenLabs, or Polly. In a voice/chat context, this creates a meaningful privacy and consent risk because users or administrators may enable the skill without realizing spoken data leaves the local environment.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

This code enables listening to speech, transcribing it via third-party providers, routing the text through an agent, and synthesizing replies back to Discord. While the behavior is described in comments, there is no visible confirmation prompt or user-facing warning in this file to inform channel participants that their voice data and transcripts may be processed by external services.

Content

No source excerpt is available for this finding.

Unsafe Defaults

Medium

• Category: Tool Misuse
• Confidence: 80% confidence

Finding

Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.

Content

Scanner excerpt · index.ts (reported line 158)May include surrounding context.

ts

if (process.env["NODE_TLS_REJECT_UNAUTHORIZED"] === "0") {
      api.logger.warn(
        "[discord-voice] NODE_TLS_REJECT_UNAUTHORIZED=0 is set — TLS certificate verification is DISABLED. API keys may be exposed to MITM attacks.",
      );
    }

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 94% confidence

Finding

The manifest explicitly supports real-time voice conversations and multiple remote STT/TTS providers, which strongly implies user audio and generated speech may be transmitted to third-party services. Failing to disclose that behavior creates a privacy and consent risk, especially in Discord voice contexts where users may not expect their speech to be sent off-platform for processing.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The default Edge voice is set to "de-DE-KatjaNeural" and the default language to "de-DE", which imposes a specific language/locale choice. The file does not document that this is optional by default, user-selected, or justified as region-specific behavior.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The comment sets the default Edge TTS voice to "de-DE-KatjaNeural," and the parser later defaults voice and lang to German values. This is a natural-language locale policy issue because the skill imposes a specific language/locale by default without offering user choice or documenting why a German-only default is required.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

When edge.lang is not provided, the code assigns "de-DE" as the default language. This forces a specific locale without user opt-in, which matches the policy violation criteria for language or locale restrictions.

Content

No source excerpt is available for this finding.
