Pywayne Tts

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward text-to-speech helper, with disclosed use of local audio tools and Google TTS for conversion.

Install only if you are comfortable using ffmpeg and, when gTTS is used, sending the text you convert to Google's TTS service. Review any package installation prompts before approving them.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Sudo/Root Execution

Medium
Category
Privilege Escalation
Content
- **ffmpeg**: Required for audio conversion
  - macOS: `brew install ffmpeg`
  - Windows: Download from https://ffmpeg.org and add to PATH
  - Linux: `sudo apt install ffmpeg` or package manager
- **gtts**: Python library for Google TTS service

## Platform Detection
