MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.90). The skill explicitly fetches and converts arbitrary web content (SKILL.md Phase 1: "URL ... Ưu tiên WebFetch" and Phase 3: "WebSearch 3-5 queries") and the code (scripts/convert_to_markdown.py, scripts/youtube_handler.py, fetch_url_title using urllib, and YouTube transcript/yt-dlp scraping) reads and ingests that untrusted public content to drive planning, chunking, and outline-generation decisions, so third‑party content can materially influence agent behavior.
