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.

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
Confidence: 70% confidence
Finding: Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
