Risk Level: SAFEINDIRECT_PROMPT_INJECTION
Full Analysis
  • [INDIRECT_PROMPT_INJECTION]: The skill architecture is designed to ingest external audio input which is transcribed into text and then passed to a Large Language Model (LLM) agent (e.g., in the GeminiAgent example). This processing chain represents a classic surface for indirect prompt injection, as malicious instructions could be embedded in audio to manipulate the agent's behavior once transcribed.
  • Ingestion points: The DeepgramTranscriber in examples/complete_voice_engine.py and the guide in references/detailed-guide.md describe receiving and processing raw audio chunks from a client for conversion into text.
  • Boundary markers: The implementation lacks explicit boundary markers or instructions to the LLM to ignore potentially malicious commands within the transcribed text.
  • Capability inventory: While the agent is not granted high-risk capabilities like shell access or direct file-system writes, it manages conversation history and generates synthesized speech responses.
  • Sanitization: No sanitization or validation logic is provided for the transcribed text before it is used as input for the LLM agent.
