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
Third-party content exposure detected (high risk: 0.85). The skill ingests outsider-authored free text from the *user-supplied Office document* at runtime—e.g., `extract_vba_macros()` uses `oletools.VBA_Parser(filepath)` to extract and pass embedded VBA source (`vba_code`) into the agent’s processing context (and later regex URL extraction), and `check_dde()`/`check_external_relationships()` decode OOXML XML/`.rels` content from the same document into readable strings.
