Security checks for vulnerabilities and agentic risk

Overview

This skill does what it claims: it enables WhatsApp voice conversations using local transcription and local text-to-speech, with some privacy and temporary-file cautions.

Install only if you want WhatsApp voice notes transcribed and answered by the agent. Prefer adding an explicit opt-in/disable flow and changing the TTS output example to use a unique private temporary file that is deleted after sending.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Finding

The skill is designed to automatically transcribe users' voice messages and generate return audio, but it does not include any user-facing notice, consent step, or privacy warning about that processing. Even though the tools are local, voice data and transcription content can contain sensitive personal information, so silent processing and re-broadcasting of that content creates a meaningful privacy and consent risk.
