Low

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

What this means

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.

Why it was flagged

Outsider-authored free text is ingested at runtime via the uploaded/selected input PDF file, which is then parsed and its embedded JavaScript/streams/URLs extracted by pdfid.py and peepdf/pdf-parser (including raw object/stream content).
