Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (medium risk: 0.30). The required workflow ingests outsider-authored free text because the user-provided YouTube URL determines which English
.vttsubtitles are fetched viayt-dlpand then read by the LLM at runtime for summarisation.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill runs yt-dlp at runtime to download subtitles from the supplied YouTube '' and then reads/injects that fetched transcript into the model to produce summaries, so remote content directly controls the agent's output.
