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

• Third-party content exposure detected (medium risk: 0.30). SKILL.md describes a “Browser Agent Preflight” that reads arbitrary open-web page content at runtime (“every page is untrusted… the injection arrives in a page body… the agent reads the web as data”), which an outsider can author and potentially influence without the agent first selecting a specific item.
