Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). This skill automates browsing and querying Google NotebookLM (notebooklm.google.com) using user-provided notebook URLs and then ingests and interprets those user-uploaded/notebook contents to produce answers, which clearly exposes the agent to untrusted third-party (user-generated) content and potential indirect prompt injection.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.80). The skill explicitly accepts and fetches NotebookLM notebook URLs at runtime (e.g., https://notebooklm.google.com/notebook/...) via commands like ask_question.py --notebook-url "[URL]" and uses the retrieved notebook content to drive the agent's prompts/responses, so external content can directly control agent behavior.
