Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.80). This skill's SKILL.md includes code that fetches and processes arbitrary external content (e.g., the "Image Proxy" example uses fetch(imageUrl) from a request parameter and multiple examples/HTMLRewriter call fetch(request) to ingest origin responses), which clearly ingests untrusted, user-provided/public web content that the worker reads and acts on.
