Low-risk findings worth noting
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
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.
