Security audit

VibeVoice TTS

Security checks across malware telemetry and agentic risk

Overview

This is a coherent local text-to-speech skill, but its script has real argument-handling flaws that can turn voice selection into local code execution.

Install only if you are comfortable reviewing and constraining the script first. Use a pinned, isolated VibeVoice environment, do not pass untrusted voice names or environment values, restrict voices to a known allowlist, and avoid loading arbitrary .pt voice files.
